302 heads and cracking

I am looking into the KB167 .030 for this teener i will be using these heads on. A buddy of mine has a burette. When i get these heads i am going to cc them and get a true number to share. If these are 60cc , with these KBs , .030", and a .038" felpro headgasket, its looking like approximately a 9.5-1 CR give or take a point. Will have to probably run 93 and a colder plug than stock i am presuming.
