400 SBC head gasket
I am at the point where i need to decide on a head gasket for my bracket motor.
It;s a 400 + 0.30, factory 509 block with brodix alum. heads. An honest 12.5 compression ratio computed with a .41 head gasket.
N/A, no power adders no steam holes in the heads
I am thinking a Fel pro 1003 should be adequate for a 600 hp level, but I would like to hear some opinions
