Cometic Ford Boss 302 .140in MLS Cylinder Head Gasket - 4.100in Bore

If you're working on a 1969-1971 DeTomaso Mangusta, Ford Mustang, or Mercury Cougar with a Boss 302 engine, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the job. It's specifically designed for a 4.100-inch bore and is intended for use with SVO heads and the M-6010-BOSS302 block, ensuring a precise fit for your high-output engine.

Cometic's MLS gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping them resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating meets the demands of tough sealing environments and various surface finishes, and it means you don't need to use any extra sealants. The center layer is stainless steel and can be varied to achieve different thicknesses; this particular gasket has a compressed operating thickness of 0.036 inches and is 0.140 inches thick before compression.
