Help with gasket choose
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
