350 motor build

okay intelligent gear heads i need some help.
Im building a 350 4 bolt main. Its bored 30 over with dome pistons with which if i had 76 cc chambered heads my compression would be 9.3 to 1. I have a mutha thumpr cam. stock crank. I originally planned on using my heads which were 76 cc chambers which would be alright putting my compression at 9.3 to 1. come to find out they are cracked. i have a friend that has a set of camel humps which are 62cc chambers what would it put my compression ratio at? I kinda want to be able to run pump gas still is all im worried about...
