How the hell can anyone answer that when you dont say what it is to begin with?

Also .20" thou of what?
Skimmed off the top of the pistons (if so what shape are they), or a thicker head gasket?

Guess you dont need it mega accurate anyway.

Basically you are looking at about 2.5cc more

So unswept will go up from 54.8ish to about 57.3

So 457.3 / 57.3 = 8:1
