Re: copper gasket ..Calling all pro's
The important thing is making sure you have absolutely flat gasket sealing surfaces. Lap the head and cylinder to assure that the mating surfaces are flat, flush and true and then almost any gasket will suffice. Trying to 'fix' a poor sealing surface with a gasket is a study in futility no matter the material.
