Cometic Ford 302/351 4.125in Bore .030 inch MLS Head Gasket

Starting with a compressed operating thickness of 0.030 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious Ford 302 and 351 Windsor V8 engines. It features embossed outer layers coated with Viton, a heat-resistant rubber material designed to handle tough sealing environments and varying surface finishes. This construction is ideal for pairing aluminum heads with either aluminum or cast iron blocks, as the multiple stainless steel layers provide strength and resist corrosion, while also handling the shearing forces between different metals.

The multi-layer design gives these gaskets increased strength and the ability to rebound, making them a solid choice for high-output applications where reliable sealing is critical. Because they are designed for maximum sealing performance, they typically do not require any additional sealants, simplifying installation. This gasket is specifically sized for a 4.125-inch bore, ensuring a proper fit for the intended engine configurations.

This gasket fits a wide range of Ford vehicles, including popular models like the Ford Bronco, E-150 Econoline, and F-150 trucks from various years. It's a well-built component for anyone rebuilding or upgrading their Ford V8 engine.
