Thread: head gaskets cut

Tweet

a lot of time gasket do have smaller holes in them .this is to keep the water slowed down in spots and put big holes in them were whey want it to move faster thru the head. i will not tell you any thing with out seeing it the head gasket companies spend money on making them fit out of the box so i am thinking he should of kept is pocket knife in his pocket less he work in R@D for fel-pro?

he cut the hole at the water passage i was wandering if cutting the gasket material would have any adverse effects on the gasket seal, the hole he cut is smaller than the open hole in the head and block, there was a hole in this location on the old gaskets
