Ok, I've measured the 6X4 heads that will be used on this build, and they came out at 94.5cc. That is with the factory flat face valves and no valve job yet. So after the valve job and new Ferrea valves(which I believe have a bit of dish in the faces), we will probably be looking at somewhere around 95-96cc and 9.3 to 9.4-1 compression, with the block zero decked, .039" 1016 gasket, and 8cc Butler/Ross Flat Too piston. I think that will come out great for this pump gas 467 with the VooDoo 704 camshaft.
