I'm trying to figure out what my compression is going to be and if I need to mill my heads. I would like 10.5:1 to 11.0:1 for my n/a build. I just had my heads CC'ed at 74cc and I plan in running a gen IV head gaskets that I believe are .027 thickness (correct me if I'm wrong) I ran the calculators and keep coming up with 12:1 is that right? Seems pretty high
