Cometic Ford Boss 302 .060in MLS Cylinder Head Gasket - 4.155in 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) cylinder head gasket is a solid choice. It's specifically made for the Boss 302 engine, featuring a 4.155-inch bore and a compressed thickness of 0.036 inches, which is a .060-inch gasket. This type of 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 for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This construction is ideal for mating aluminum heads to cast iron blocks, as it can manage the shearing forces that can occur between different metals. The center layer is uncoated stainless steel and can be varied to achieve different thickness requirements, like the .060-inch size on this particular gasket.
