Cometic Ford Boss 302 .056in MLS Cylinder Head Gasket - 4.030in Bore

If you're rebuilding the top end of your 1969-1971 DeTomaso Mangusta, Ford Mustang, or Mercury Cougar, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice. It's specifically designed for the Ford Boss 302 engine, featuring a 4.030-inch bore and a compressed thickness of 0.056 inches. This gasket is built to handle the demands of high-output engines without needing any additional sealants.

Cometic constructs these MLS gaskets from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is designed to seal effectively even under tough conditions and on various surface finishes, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron block configurations. The center layer is uncoated stainless steel, allowing for precise thickness requirements.
