Ok so the machine shop has verified that the block is sound. It has been magnafluxed and sonic checked and all is well for the 0.030 overbore. Now I need help here, I would like my compression to be around 11.0:1. I was thinking about the 63 CC Edelbrock RPM heads and the Scat forged 416 kit (1-48013). I know that the head gasket will effect compression as well so we can adjust the thickness to vary compression ratio a bit. Any input would be greatly appreciated.
