The heads are off... i already had the gaskets chillin in the closet from when i was going to use them on my bolton build so as far as wasted money that isnt a factor. I wouldnt go and tear a running car apart to throw these on for sure.

pretty sure a shim is .015 thickness last time i checked. And if that's the case that compression doesn't become a factor, why does lloyd ask for compression ratio when picking out a cam, and when he does he trys to use thinner gaskets to get more compression for the cam. If i thought it was worth my time id dig through emails to show what he has to say about that kind of stuff. Daves compression is a little down because he had to swap blocks (original was decked) and heads have a slightly larger combustion chamber then expected with that said his tune/cam/head set up was set up for a certain number when moe did the tune, and lloyd spec'd the cam. The easiest way at this point to get that lost compression back is to use a shim.

I'm lost so I gotta ask. OP what exactly are you trying to do? Are you running a LT1 w/ LT1 style heads?

Just trying to get things sorted out here.

LT1 with TFS 195 Heads. The .15 shim is a SBC head gasket.(They dont make one that thin for LT1'S) I can use them with a little trimming to make them match. SOOOO all i was asking was if some people who HAVE done this took pics so i could get a general idea. YES ive already traced the diff part when matched up. But its always nice to double check.

OK I was confused. I didn't know anyone had modified a SBC head gasket for a LT1.

Wouldn't it be easier to have the heads shaved some more? I'm just asking don't hate. LOL.

Are we sorted out boss man? lol The shim gasket is all metal and should hold up better with a 200 hp shot of NOS.
