0001103 Cylinder head gasket set. .020" copper

For the serious Flathead builder, these Samwel cylinder head gaskets offer the traditional sealing performance of embossed copper. This set is designed for 1937 to 1948 74-inch and 80-inch Big Twin Flathead models. With a final crush thickness of .020 inches, these copper gaskets provide excellent heat transfer and a reliable seal for the high-compression demands of a vintage sidevalve engine. They are a direct replacement for OEM 16769-36 and 11-36A. In the shop, we prefer copper for these applications because of its durability and ability to conform to the cylinder and head surfaces.
