THOSE CHEAP HEADS FLOW PRETTY GOOD OUTA THE BOX, A LITTLE CLEAN UP AND A GOOD VALVE JOB,PORT MATCH AND THERE GOOD TO GO

@charleslowe522

If I had a use for them I would order a set in a minute. Interesting thing though, the heads found on the 4.3L v6 Vortec motor found in Chevy light duty trucks flow quite a bit out of the box and with a clean up will flow over 300 CFM easy and that's more that the aftermarktet heads found for a Grand National or the Buick Stage 2 heads. The heads from GM parts direct, are cheap. Only $168 for a pair, that is crazy and they are made with very high quality and engineering. The trade off, well you have to do a lot of custom work to swap the 4.3l v6 vortec into a Grand National for instances.

Multiple companies use these heads skip white , assualt racing , rcp ect. There's a big thread about them on the third gen forum buget assualt racing head. They actually look just like dart platinum heads too. My set has either the vortec or early version intake bolts . I had choice of angle or straight plug and with or with out steam holes when purchased. They cost allot more than 186$ in 2016. Solid head though. I port matched a 1266 gasket to my single plane efi intake. My heads are raised runner ports. I bought mine bare too. I lapped all my valves . I own a machine shop. In the tread I mention I put a set on a surface plate and belive they were flat with in .0004 ten thousandths . I've had my set on my gen 1 sbc 383 with a s488 turbo since 2016. No issues.

Damn, back in the day, we couldn't have even imagined getting a head as good as those DNA heads for anywhere near those prices. Holy hell the world has changed - haven't priced aftermarket aluminum heads since the mid-90's for SBC.

Check the thickness of the upper wall, inside the intake side, on the short side of the valve radius. We made a lot more horsepower with a higher top wall there. It’s even more pronounced with 351 Cleveland heads for fords, BUT, ( on Cleveland heads) because of the volume inside the runner, it’s best to put vanes inside the runners. This is done by drilling a hole in the bottom of the intake runner and running a threaded shaft, which is attached to the “vane” ( a piece of thin curved metal, much like what’s in torque converters), and after tightening, silicone. You have a flow bench, put your finger in front of the intake runner (or a popsicle stick) to see the difference. Ultimately you’re wanting to direct flow to the short-side radius, heighten the top of the runner, to streamline flow into the combustion chamber and create a better “mix” ( volumetric efficiency) in the chamber.

@christianmotley262

2 жыл бұрын

Have thought about doing that for years, you're the first I've heard of using vanes. Are you talking about a carbureted setup and if so, what does the fuel do to the silicone? On the old Buick heads we have been taught to leave the short side radius alone, BTW.

Nicely done.

2023 update: these heads are currently running $243 as of 12/27/2023. Pricing history shows they fluctuate (like most Amazon stocked items) between $203 and $260. So if you're thinking about playing with these, keep an eye out for the lower end of the scale.

I picked up a set of “Deepmotor” aka Chicom copies for $380 190cc int. runners & 64cc chambers and I did have to clean them up a bit (they’ll run fine I’m just ocd) but I picked up more power than $400 should have gotten me. I’d rather buy from an American company but I’m not wealthy so these domestic producers like AFR or Edelbrock etc... need to come out with actual budget heads if they want to retain customers that can’t afford their heads even when they’re used let alone new

I love the older engines with the newer heads. Basically anything from the D port 113 corvette heads on up. The old camel backs and 882 heads were Heavy gas guzzlers that only flowed well after some serious work. That said I have a four bolt truck block 355 with unshrouded 202 190 valves , Ported 882 heads at 9.5:1 screw in studs and guide plates and bronze guides. That’s only because I did them myself twenty years ago and they are still like new and run really well. Vortec and 113s are better truck heads though. I also have a 327 with camelbacks just for nostalgia. I have one Chevelle, one Xj6c jaguar, and one truck but I seem to have collected and built at least a dozen engines for some reason.

there is a 90% chance those heads are made in the same place lol

I have a question on these spring kits. They allow you to use a higher lift cam without any additional machining? What kind of lift are we talking about? Can they be used with a hydraulic roller cam? I've got a GM crate 330hp 350 with vortec heads with only about 4K on the mileage and would love to buy a kit that allows for the addition of a roller cam and lifters around the .550 lift range. Block is already set for roller setup.

Rough intake runner is a good thing on a street motor

Another great video! Now if you look at the average flow numbers of both heads they're within 3.3 CFM. It was 196.728 average CFM for the DNA head and 200.028 CFM for the AFR head.(from what I could read on my phone, they might be slightly different if someone can see them better?) You can't overlook or underestimate the low lift numbers because the other head has better high lift numbers. Unless you're running a very high lift cam, you probably won't even hit the highest lift numbers once but the low lift numbers will always hit twice once on the way up and once on the way back down. If someone were to use a cam with .500" lift using the average flow numbers then the DNA heads would average 176.5 CFM and the AFR heads are 176.4 CFM. So if a larger cam or porting aren't in the budget, the DNA heads would be the ticket because both sets of heads would probably make right around the same HP with a. 500" lift or lower cam.

What's your take on the aluminum ATeam performance heads from Amazon??

There's other factor like cc of the head when making a choice. Velocity is very important also. That said I'll take the AFR heads all day sure vs a cheap head like this. If it's a mild build and not really beating on it I guess they're ok and have a place. My little sbc with AFR 220cc makes 637hp on pump 93 with a hydraulic roller on a mild tune. Although anyone looking for the baddest 23 degree sbc head BES ALL PRO RR245 are where it's at. From .700 thur 1.000 lift they flow about 370/292. They only start at 6,700 though lol.

Here's a tip... Just clean up the exhausts, shape the lower side and the area flowing out with a match port, especially at the bottom. I'm not into 5 angle valve jobs, because 3 angles with blended top and bottom angles flow better. You may also want to increase the throat to 75 to 80% if you have a lift near .600. On the intake side. Match port the runners in an inch or so, blending into the existing ports flow. Clean the rest of the runner up. 3 angle valve job blended and you are good to go. If you have some lift, hog the bowls to the flash then clean the flash area around the guide, then round your guide. It's a weekend project if you don't do this for a living. I'm a machinest and it takes me an a day. If you can spare a few CC's unshroud the valves in the chamber and at the plugthreads. It will cost you 2 to 3 CC's but worth It On the flow results I've seen. If your not going vortex, remove the upper lip at the top of the intake gasket. The intake side are based on vortecs. I can speculate on the exhausts. Heres something that they don't tell you. They take 16 + .100 valves.

I’ve seen 420+ cubic inch small blocks with a CNC ported 195 AFR that work damn well. 👍🏻

Got a part number for the knock off heads I'm in need of a set! I'd like to replace my 186. 300 hp heads and go aluminum and maybe a hydraulic roller in my ole tow truck

Wow, ill be damned huh. Great stuff cutter. How much would you base power off of the percent of flow. Those DNA heads flowed 77% where the afr was 68%. Love the info, keep it up, stay safe

Thanks brother! A rough theoretical calculation is 2hp per cfm So they could support 500hp

Please list the costs of each set of heads in the future.Some guys,such as myself,would like to compare them price wise.So they could decide if the extra flow is worth the money on there combo.Thanks!

Help a Cheap Skate out ! ! ! I have a '55 2 door Post and a Disco Corvette that needs some motivation . . . a Beehive setup would help get either project closer to Drivable . . .

Look out for the next video!

How do I property get a set of marine speced vortec heads for my freshly built roller sbc 350 for my 1994 SeaRay 220 BRS?

What are the flow numbers on edlebrock rpm heads? I have rpm heads on a 383 and they are only like 170 intake runners and I think they are to small for the 383 and probably are starving it at 6000rpm. I want to upgrade to a bigger head without breaking the bank

@port nut it is definitely a torque motor.

And if you cleaned up the rough spots on the intake and exhaust would probably flow even better huh??? Looked at a bare set for a 400sbc I gt on the engine stand

DNA All the Way and port them with maybe a polish on the exhaust side. Thanks for the Heads-up

I need them

Looks like they were made at the same exact plant except didn't meet afr's quality control standards so instead of AFR melting them back down they sell them wholesale to DNA and DNA probably finishes up the machining but skimps out as much as they can that's why the vapor ports and vortec threads aren't drilled not to mention all the casting flash! I would honestly buy the cheaper heads then do some mild porting and clean up on them!

More like AFR buying DNA's best

@@dalestephens5176 DNA is just a reseller, just like AFR. others like AT racing and KMJ performance also sell versions of these castings.. The version I bought from AT racing has clean casting surfaces just like the AFRs and they also were under $400 for the pair. the dna has different casting and machine work as well. the AT racing heads have the same shape runner ports as the AFR's

I can't find the video where you built and dynoed the 350 you put these on. What did it end up making?

Was just dynoed, video's coming up. NA and boosted

I had a feeling these DNA heads were quality control biproducts from another dealer. I would love to have a set of those spring kits for my 85 third gen build.

Where did you get these dna heads? I don't see them.on amazon unless they came bare and the price jumped up a ton

Amazon and yeah bare castings, like is said in the video im adding USA made valves, springs ect. Just ordered another set to play with

On the DNA head is it true that it must use +100 length valves or standard length? Also what rocker studs do you use.

Yeah i ran .100 longer valves on these for proper installed height with my setup. I will be making a video with everything i used on these heads. Just finished them up the other night

Would love to see the enforcers on actual dyno on a 383 or so to see real horsepower numbers. Nobody seems to have done one yet.

We currently i am using a DNA aluminum head (voted by the viewers) on a 355 SBC. Its basically exactly the same casting as the afr head

Awsome I could use some

I could use them springs myself. Great video man. You will capture a BIG audience aiming for the hot rodders on a very limited budget. Soon to be 100k no doubt.
