Cometic Ford SB 4.030 inch Bore .036 inch MLS Head Gasket (w/AFR Heads)

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed thickness of 0.036 inches and designed for a 4.030-inch bore, specifically intended for use with AFR heads that feature a coolant eyebrow. MLS gaskets are a solid choice for high-output engines because they offer maximum sealing performance without needing any additional sealants. They are well-suited for applications where aluminum heads meet either aluminum or cast iron blocks, as they can handle the shearing forces that can arise between dissimilar metals.

The strength of these gaskets comes from their construction, which uses multiple layers of stainless steel. This design also allows the gasket to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit. Viton is chosen for its ability to perform in demanding sealing environments, under various load conditions, and on different surface finishes. The center layer is uncoated stainless steel, and its thickness can be adjusted to meet different sealing requirements.

This gasket fits a wide range of Ford Windsor V8 engines, including popular models like the Ford Bronco, F-100, and E-Series vans. It's a well-built component designed to ensure a reliable seal for your engine's top end.
