I'm using the hypermax headgaskets on a 6.0 that i'm building for a guy I know.I've had heads o-ringed before but this is the first time trying these gaskets.Just wondering if anybody else has used them before?
Quit drinking those heads are flat!!!I have seen alot of the heads that are poor machining from the factory. I have seen them so rough it was horrible and they were six thousanths out of flat. That will never let an MLS seal up. I own four sets of heads and they were all far from flat. I have one set that is so cracked out also, between all valves and to all glow olug holes.
