Hi there, Thank you for the reply, as I learned something new.. ANother question, if you don't mind the asking, excatly what kind of silver paint do you use? And is this method still the best way to do the head gaskets? I've heard of people using the copper gasket paint spray.. What about that? Thanks, Norm '89MTX, '93MTX, '93ATX, and '99 Mustang Cobra
