Threebond

[Graham]

If your having so much trouble with oil leaking from the head and base gaskets then maybe you need to drop the 750 gears with all that oil pressure?
I never heard of Gasgacinch and I would never use Threebond on a head gasket. I use copper coat on steel, aluminum and copper head and base gaskets if needed. But I do mostly repair and mild performance work.
Ray is the performance guy here and should have the answers you need.

I had case glue used on a head gasket before and almost ruined the head trying to remove the %^&* thing.
