I use a good quality cork gasket. Glue to a straight flange with yellow 3M, coat head side with Permatex #3 (Super 300), let it soak in, coat again & install with Corvair valve cover springs (load spreaders, but not chrome). Re-tighten after a year or two. They will leak again about 20 years later. Never had much luck with the neoprene ones. With the Permatex, they come right off, even after years.
