Cometic Ford 385 Series .045in MLS Cylinder Head Gasket - 4.500in Bore

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Ford 385 Series engines. It features a 4.500 inch bore and a compressed thickness of .045 inches, making it suitable for a range of Ford and Lincoln vehicles from the late 60s through the 90s, including models like the Ford F-250 and Lincoln Continental. MLS gaskets are built for high-output engines where reliable sealing is critical.

Cometic constructs these gaskets with 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 handles demanding sealing environments and various surface finishes without needing additional sealants. This construction is effective for mating aluminum heads to aluminum blocks, or aluminum heads to cast iron blocks, as it can manage the shearing forces between different metals. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .045 inches found in this particular gasket.
