I am trying to get and idea of my compression ratio on my 355.
350 block .030 bored
Flat top Diamond forged pistons with 2 valve reliefs
6" rod and piston is .020 in the hole
Edelbrock rpm heads with 64cc
Felpro 1003 head gasket .041 thick
Let me know if any more info is needed and thanks in advance for any and all help!!

gasket bore is estimate.
but this should be very close.
