That will put you somewhere between 9-9.5:1 compression. How much boost are you running?

depends on your setup, what are you using for control?
are using standard 75 mm pistons
std bore already?
is the head shaved or trimmed?
when you rebuild a head they shave a couple thousanths off to true it.

changes your cr besides the headgasket

what size turbo? what trim?

this thread will go in circles if you don't specify your setup fully

hop on this thread & read, chances are someone may already be runnin your setup
