I have my 7.4's out of my old ls1. Running stock 317's, but with a mild custom grind comp blower cam that was spec'd for a ls1, also have LS9 gaskets, I read the compressed thickness is .055. I am unsure on the base circle of the cam. I also have trickflow pr checker, that is based solely on the wipe pattern on the valve tip. I got the instructions straight from their site. I borrowed it thinking it was based on the number of turns on the checker.

I have always heard that the stock pr's are 7.38, but a lot of guys think that they're 7.4. There's another thread going in the internal section where one of our members is going to measure one of his stockers and report back so we know for sure.
