Cometic MLS cylinder head gasket for the Ford 221 Flathead V8, .051" compressed thickness with a 3.156" bore and 21 studs. Intended for dependable sealing in higher-output engines without additional sealants. The gasket uses multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated center shim. It tolerates aluminum-to-aluminum or aluminum-to-iron interfaces, rebounds under load, resists corrosion, and helps reduce bore distortion.
