Cometic Ford 289/302/351 4.080 inch Bore .040 inch MLS Head Gasket (Non SVO)

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Ford 289, 302, and 351 Windsor V8 engines. It features a 4.080 inch bore and a compressed thickness of .040 inches, making it suitable for a wide range of classic Ford vehicles like the Ford Bronco, Ford F-Series trucks, and even some De Tomaso models. These gaskets are built to handle the demands of higher output engines and are designed to provide a strong seal without needing additional sealants.

Cometic constructs these MLS gaskets using multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction is ideal for mating aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals. The center layer is stainless steel and can be varied in thickness to meet different engine build requirements.
