David Vizard has a KZread where he said he did 2.02 and 1 6 valves in a e7te head with extensive port work and got 280cfm. It was him saying it. I don't think you can count on getting that number but many ported e7 heads are around 220 to 230 cfm or around some cleaned up gt40 iron heads.

One of my favorite videos

Thank you Richard. Isn't this the same test as MM&FF magazine did years ago ? I still have all the magazine's. Nice to see it in video form now.

Regarding your question on spring pressure on HR cams. I came to the conclusion too much was better than too little. Less wear and chance of lifter failure from float was my conclusion. More power because no valve float. I went with a 450 lb/in rate spring. Its fine.

I appreciate the milder version of the 5.0 as it represents a good combination for street driving with an automatic transmission.

Other fantastic features were the --- factory fitted roller rockers, proper headers, 70mm throttle body, massaged upper and lower intake manifold, hot tested.

Awesome information thank you

Two ways to look at the valve float issues with these heads: One is that they all provide insufficient valve spring pressure. Another is that the Comp XE series of cams push the boundaries of ramp velocity for street cams, requiring higher spring rates than most. All of these heads would work okay with a lot of aftermarket cams, including some of Comp's less-aggressive profiles. Choosing ramp velocities will always be a balancing act between increasing performance versus increased wear, noise, and valvetrain upgrade requirements. These days most folks are opting towards the higher ramp rates; as Richard suggested, head manufacturers mostly have followed the trend by increasing their spring rates. The takeaway is to match your springs to your cam maker's recommendation rather than settling for significantly lighter (or heavier) springs that happen to come on your heads. Economically, most of these heads can be purchased bare if a spring change will be required.

Older stuff of YOURS, but still a good watch and a nice relief from all the political talk. And I mean nothing bad in that as your info from then, is still just as real now. Over time you almost forget where we came from on heads. I still have my Windsor Sr from SuperShops in the garage. At the time, IF you couldn't step up to some highports it was about as good as it got for 1990. When 250cfm was great and 6500rpm of hyd roller was dreamy. Can you imagine telling some guy in 1990 that we'd be doing nearly 8000rpm with hyd rollers LOL. Esp the poor Chevy guys...... rem the helper springs on top of the lifters? Keep it coming, Richard!

Ford never offered alum factory heads on the 5.0L

Ive been looking into buying another of my original car, way back in the 80s… a 78 LTDII, that had a 351M, and had the option of a 400. Same for the next car, a 78 Cougar XR7 with a 351W. I was also scouting for a better engine/trans option, like a 351w, that doesnt require a lot of money, and I just discovered there is a Ford 534, late-50s thru early 70s, I think, that was used in big trucks and even used as a tank engine. Of course, I had to investigate this new thing. At something like 1300lbs, obviously its a MONSTER, and obv too big and heavy for most cars, like a mid-70s intermediate. Then I saw, in marine form, with dual turbos, it made a max of 400hp, so they already made a sort of performance version. Im curious if anyone has hotrodded one of those. Aside from the weight, it seems like it would be a natural to try beefing it up.
