Blackwater knows the kind of gasket I'm talking about. When I worked in the Olds garage, those were the kind of gaskets used on Olds V8s. They were just sheet metal with a coating that looks like silver paint. We always sprayed both sides of the gasket with Red Hi-Tack. Never had any trouble. I just wondered if 230-250 engines used them from the factory or always used composite head gaskets. If they ever did use that type of gasket it would be an easy way to help raise compression. Jay
