Cometic Ford Boss 302 .036in MLS Cylinder Head Gasket - 4.080in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built for the Ford Boss 302 engine, featuring a 4.080-inch bore and a compressed thickness of 0.036 inches. It's designed to provide a strong seal for high-output applications, making it a solid choice for your 1969-1971 DeTomaso Mangusta, Ford Mustang, or Mercury Cougar. The MLS construction uses multiple layers of stainless steel, which helps it rebound and resist corrosion, while the outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes.

Because it's made from multiple layers of stainless steel, this gasket offers increased strength and can handle the shearing forces between aluminum heads and cast iron blocks, or between two aluminum components. The Viton coating on the outer layers is effective up to 482 degrees Fahrenheit (250 C) and meets the demands of harsh sealing conditions. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, though this specific gasket is set at 0.036 inches compressed operating thickness. These gaskets are designed to seal effectively without needing additional sealants.
