Cometic Ford Boss 302 .045in MLS Cylinder Head Gasket - 4.155in Bore

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for specific Ford Boss 302 applications, including your 1969-1971 DeTomaso Mangusta. It features a 4.155 inch bore and a compressed thickness of 0.036 inches, intended for use with World Products Man-o-War blocks and SVO heads. MLS gaskets are built for high output engines and don't require additional sealants, making them a solid choice for sealing aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as they can handle the stress between different metals.

The construction uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes. The center layer is stainless steel and can be varied to achieve different gasket thicknesses, like the 0.045 inch bore on this particular gasket.
