Help with gasket choose
Help with gasket choose So two different company told me two different gaskets to get for my stock ls2 with 317 heads to 9:5:1 compression, the is a turbo build project
The first guy said: Bore: 4.130 with a .060” thickness would yield an approximate compression ratio of 9.55:1. Bore: 4.130 and .070" thinkness will result in a slightly lower compression ratio of 9.36:1.
the second guy said It would require a .080 gasket which is really thick so we don't recommend it. , also, it would be custom
So which one would get me to my goal? thanks for your help

Ls9 gasket is around 4.1 bore .051 compressed.
Generally, prefer to keep gasket as thin as possible. Even with forced induction. Keeping the quench close to a .035-.040 area is known to be very beneficial for many reasons. In both n/a and forced induction engines.
The GM LS9 gasket is affordable,reliable and has proven great results so far.
