Them said to be 11.1 Domed Pistons do not nearly make that much compression in a 327 Build . do some cc-ing and check the math with the type of head gasket your going to use before you mill the tops down . I Left mine alone .

CC-ing? I have no clue how to measure for compression. I think what I will do is pull the heads off as I need to pull the Offy intake that's on it right now so i can put on the 69' Z28 intake I picked up. While it's off I can just pull the heads and run the motor and heads over to an engine shop and see if they can help me out.
Are you saying my compression may be lower with the domed pistons because it's a 327? Why?
