On my 1942 Mercury I am having has gasket problems, block and heads were mechied, got a set of Best Gasket copper sandwich head gaskets witch just wicked coolent, they had copper spray on them but the coolent just soaked thrugh the fiber, then I fitted a new set of Fal-pro gasket with were a nightmare and I had bubbels in the radator and water in the bore.
All I can find is NOS asbestos head gaskets, they have steel reinforcement and steel fire rings, I am just worried about if I ever have to take the heads off again they will stick to the block and I will need to scrape them off,
Should I use copper head gasket spray? I refuse to use grease or sliver spray paint, or should I slap them on dry?
