As above anyone know how to calculate lower compression ratio with a thicker head gasket?
And if so what thickness plate Would I need
Anyone ran a doubled up oem gasket bla bla

Surely doubling up on headgaskets will lower the compression... Why would you want to do that?

11:1 compression ratio is no good for boost

11.1 is excellent for boost, well around 10.75 I think I'm at with the reworked head and thicker gasket. 11:1 arias pistons. Rich at paw did the calculations so no help to you.
