Went on the Dyno today, basic 5.7L

Goody,

Cometic makes headgaskets in multiple thicknesses, I have the math someplace but I think with a .074 thickness it should be 10.8:1. Summit has the gaskets.

With the eagle heads you can run either the 6.1 or eagle intake, but the eagle intake will hit the coolant sensor in the block and you must use spacers. My understanding is that the 6.1 intake doesn’t hit, so no spacers necessary.
