The Cylinder Heads for My 6.0L Swap Have Arrived! (243 Heads)

Автокөліктер мен көлік құралдары

I am beginning to find and spec all the parts I need to start the 6.0L LS swap for my 2002 Silverado. A significant key to the success of this build is the cylinder heads I choose. I did my research and found that the 243 design will work very well. I got a set of 243's from eBay, and I wanted to share that with all my viewers.

    I'm building the 6.0 up in my Hummer h2. I know there's nothing on the planet that will make that car fast. I just want a little more responsiveness from it. And I researched all of these heads (and cams) and I'm going with the 243. But my man, I just want to say that this was the only video that I found where they actually had a side-by-side comparison and not just computer animations. Thanks for taking your time to put this out there. God bless

    Thanks for the 243’s video. I put new 243’s on my Hummer H2. 6.0 lq4. I was told by the tuner guy that I have too much compression because I added a summit truck cam for lower end torque. Any suggestions on how to get better performance out of my engine. I do have a cold air intake. I wanted to do long tube headers but haven’t done that as of yet. My performance sucks. And I’m getting misfire’s now. Any suggestions, Thanks.

    That is a good question I am currently doing a cam swap on my hummer H2 as well. I just put in the 317 heads on it but I wanted to get some more performance out of a head I just try to do some research on which head I was told the 706 was a good combination for the cam that I’m putting in but I’m still trying to gather more information before I make my final choice

    You got some other problems. Not sure what but a head and cam swap should not be causing these problems.

    317 and 243 are supposed to have similar intake flow rates. 243 have a better intake runner finish. The advantage is that 243 have a smaller combustion chamber yielding higher compression. The 317 chambers are way over sized. The solution is to mill down 317 heads if you don’t want to buy totally new heads

    Are send those 317 to Texas speed for a stage 1 port job on them. I'm waiting for them to send my 243's back. I had a stage 2.5 port service done that I want to put on my 6.0.

    Built this for the future, as well as this truck not capable of running e85 yet. Not looking to run that type of compression in a boosted setup so these heads are on the money for me.

    286 heads are what I'm looking for in my build. LS1 std bore, 4"stroke makes it 383. Redux ITB's and 1&7/8 long tubes. Building for torque and economy. With the occasional burst. It's a daily driver street sedan. But finding those heads here in New Zealand is a nightmare, import costs are mad to frustrate things further. Easily found, but Dame expensive to get here
