Cometic Ford 221 Flathead V8 .070in MLS Cylinder Head Gasket - 3.156in Bore - 21 Stud

This Cometic Multi-Layer Steel (MLS) head gasket is built for the Ford 221 Flathead V8 engine. You get a gasket with a compressed thickness of 0.070 inches and a bore size of 3.156 inches, designed for 21 studs. It's constructed from multiple layers of stainless steel, with the outer layers treated to a heat-resistant Viton rubber coating. This construction helps it handle the stresses between different metals, like aluminum heads on cast iron blocks, and it doesn't require any additional sealants for installation.

The stainless steel layers give this gasket increased strength and the ability to rebound, while also resisting corrosion. The Viton coating on the outer layers is a tough material that can handle harsh sealing environments and varying surface finishes, staying effective up to 482 degrees Fahrenheit. The center layer is uncoated stainless steel and can be varied in thickness to meet different engine build requirements. This gasket is a solid option for many Ford and Mercury vehicles from the late 1930s through the early 1950s, including models like the Ford F-1, Ford Customline, and Mercury Monterey.
