Questions about 317 Head Swap
I'm getting ready to put a set of 317's on my 98' SS to lower the compression for the turbo kit going on. My question is what head gaskets do I use? I already ordered and received a set of GM 5.7L MLS gaskets from thunder racing (p/n 20-12589226). I held them up to the heads and they line up perfectly with the combustion chambers as well as the other holes in the bottom of the head. Yesterday I came across a thread on another site stating you need to use the 6L gaskets. Can anyone confirm if this is true? I would think (and I'm usually wrong) that since these are sitting on a 5.7L block, you would use those gaskets. The 243's off the ls2 (6L) use 5.7L gaskets so why wouldn't these? I just don't want to have to take the heads off twice and screw something up. Let me know your thoughts.

Interesting. You are probably referring to my thread on LS1Tec where I was looking for the same info and got that response. Kinda makes one wonder don't it?

Yea it really does. Like I said, I have the 5.7L gaskets and they line up perfect. I don't understand why I would need to use the 6L gaskets and what the difference would be if these line up. Hopefully someone with experience will chime in.
