Cometic Ford SB 4.080 inch Bore .040 inch MLS Head Gasket (w/AFR Heads)

Starting with a compressed thickness of 0.040 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious Ford Windsor V8 engines, especially those fitted with AFR heads that have a coolant eyebrow. The multi-layer design uses embossed stainless steel layers, with the outer layers coated in heat-resistant Viton rubber. This construction is key for sealing performance in high-output applications, handling the shearing forces between aluminum heads and iron blocks without needing extra sealants.

The strength comes from those multiple stainless steel layers, which also help the gasket rebound and resist corrosion. The Viton coating on the outer layers is designed to handle tough sealing environments and varying surface finishes, with a heat resistance up to 482 degrees Fahrenheit. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, making these gaskets adaptable for various builds. This gasket fits a wide range of vehicles, including many Ford Broncos, Country Sedans, and Custom models from the 60s and 70s, as well as other makes like Chevrolet Impalas and Camaros from the same era.
