Cometic MLS cylinder head gasket for the Ford 221 Flathead V8, .040" compressed thickness with a 3.156" bore and 21 studs. It seals combustion and coolant passages for high-output applications and does not require sealants. Built from multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated steel shim, it resists corrosion, handles thermal mismatch between aluminum and iron, and distributes clamp load to reduce bore distortion.
