Ah, but this has a copper head gasket anyway. And it must be magic. Flipped the head over to clean and check it out and almost threw up. What, how, why, who? (Photo taken after wet lapping the flange on 400 grit glued to plate glass.) Someone deserves some severe karma from this. And, this was found after installing helicoil in case for stripped base stud and making a mandrel to properly tap in the cylinder-to-head dowels.Spray on copper coat works very well on head gaskets
But. It had pretty good compression!
