Speedmaster Small block porting tips and results Part 1
SCE has an intake gasket, part # ending with a "P", that we had them cut for us and it's in their catalog...it allows a nice gasket to be used with a taller intake port opening than anything else that I'm aware of. I do that instead of tubing the pushrod holes cause it don't take much for a leak to happen. You can gain approx. .180 at the top just by porting to the gasket line.
