Best copper cylinder head gaskets consist of one layer of copper and steel on the other side for this application. Excellent torque retention is achieved by using superior materials. Best copper gaskets are definitely “old-school” but with a modern flair for better performance. They are such works of art, we almost hate to sell them!
