Curious about my 85 6.9l f250 exhaust manifold gasket surfaces. With new heads, I want to make sure I prep the ex. manifolds correctly. Is there supposed to be a concave ring on the manifolds? It appears that way in some spots, but not others. What is the correct way to mount the metal gaskets, with or without copper spray gasket?? I degreased and sandblasted with not much luck, any wisdom would be greatly appreciated!
