Ok, back on the road! Still not sure about the head gasket.. Thanks to Jonathan Taylor for helping me do the coolant pressure test.. We put 16psi in it and it really didnt go anywhere.. We did a leak down and every cyl was 10% leak down accept one.. Cly 5 was 20-25.. Not great but not terrible..

Gabe why are you not sure about the head gasket?  For cooling system pressure test on our prototype engines, we pressurize the cooling to 40psi and the acceptable criteria is less than 1 psi of pressure drop over 5 minutes. This is a little overkill but dyno time is much more expensive than build time.

Anyway, car looks great, hope to catch up with you while im on the coast.
