Cylinder Pressure

You can use those......but I would NOT deck the block anymore than to square it and even it up on both sides. They are always tall. At the stock deck height, the Speed Pros come to like 8.2 dynamic with that cam.......and I am using 72 CCs for the heads and that's probably a little big. You may have to end up using a thicker head gasket.....but they are certainly available. You just won't know exactly how to get there until you know where the deck ends up and the size of the chambers, but I have no doubt you can get to 9:1 even. With no quench, I wouldn't go any higher than that. Using a .060" head gasket and the piston .012" in the hole I get 9.0 static and 7.9 dynamic. That would be perfect. I get the .012"figure because that's where the Speed Pros sit at stock deck height. Hopefully it will clean up tall and that will give you a little wiggle room. Doable for sure.
