Never had a leak or cracked neck from using sealant instead of gasket. The Best brand head gasket referred to is called GraphTite. Is has Kevlar layer in it also. I have never seen a GraphTite failure. I have seen a copper gasket failure recently. Any gasket will fail if your block and or head is not flat. Speaking of reference to information in Les Andrews book, ask Les what he recommends using now. I met Les and talked with him in length at the MAFCA national convention this year in Sparks, NV. We talked about head gaskets and he advises to use the GraphTite gasket.
