Cometic Ford SB 4.100 inch Bore .040 inch MLS Head Gasket (w/AFR Heads)

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Ford SB engines with a 4.100 inch bore, specifically when using AFR heads. It's built with multiple embossed layers of stainless steel, and the outer layers are coated with Viton, a heat-resistant rubber material. This construction helps ensure a strong seal, even with aluminum heads on cast iron blocks, and it doesn't require any additional sealants.

The gasket has a compressed thickness of 0.040 inches. The multi-layer steel design provides increased strength and resistance to corrosion, while the Viton coating handles harsh sealing environments and varying surface finishes. The center layer is uncoated stainless steel and can be varied to meet different thickness needs. This gasket fits a wide range of Ford vehicles, including models like the Ford Bronco, F-100, and E-Series vans, as well as AC Shelby Cobras and De Tomaso Mangustas.
