Cometic Ford SB 4.080 inch Bore .066 inch MLS-5 Head Gasket (w/AFR Heads)

This Cometic MLS-5 head gasket is built for Ford SB engines with a 4.080 inch bore and specifically designed to work with AFR cylinder heads. You get a multi-layer steel gasket with embossed outer layers coated in Viton, a heat-resistant rubber material. This construction helps ensure a strong seal for high-output engines.

The multi-layer steel design offers increased strength and resistance to corrosion, while the Viton coating on the outer layers handles demanding sealing environments and surface finishes. The center layer is stainless steel and can be varied to achieve different thicknesses, with this particular gasket having a compressed thickness of 0.075 inches and a nominal thickness of 0.066 inches. This type of gasket is suitable for mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can manage the shearing forces between different metals. It's designed to provide maximum sealing performance without needing additional sealants.

This gasket is a solid option for a range of vehicles, including models like the Ford Bronco, Ford Econoline, and Chevrolet Camaro from various years. Always refer to the manufacturer's installation instructions for the most accurate fitment and installation details for your specific application.
