Headgasket for Kb399 and 302 Heads
Thanks!! I'll reach out to comp cams. I did a similar measurement for them so I could get max lift on a 383 cam I built with old school trw dome pistons.
Predict piston-to-valve clearance before ordering a cam with a valve-drop test
I think I'm good on all other clearances and should be fine with an .039 head gasket. I do see why Keith black states these dome pistons can't be used on magnum heads or closed chamber aluminum heads. I think the 302s are as closed chamber as you can get.
Doing a quick check that puts compression ratio roughly at 11:1.
