New heads

Please explain the 10:1 pistons. Do you have a brand and PN? Are they in the engine now? And tell us how you intend to use this engine, and the cam.

If you have pistons that are 10:1 with stock open chamber heads, then if you put on EQ's or Edelbrocks or LA-X heads with the much smaller combustion chambers, then your static compression ratio will shoot to over 11:1, and, for street use and a mild cam, your Dynamic CR will be too high and the engine will detonate.

Do you want iron heads or aluminum heads?
