Cometic Ford SB 289/302/351 4.2in Bore .060in MLX Non-SVO Head Gasket

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Ford small block engines like the 289, 302, and 351 Windsor V8s. It has a 4.200 inch bore and is .060 inches thick, intended for non-SVO applications. These gaskets are built to handle the demands of high-output engines, providing a strong seal without needing additional sealants. They are suitable for combinations of aluminum heads with either aluminum or cast iron blocks, as they can manage the stresses that arise from dissimilar metals.

The construction uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is designed to work well with various sealing environments, load conditions, and surface finishes. The center layer is uncoated stainless steel, and its thickness can be varied to achieve different compressed gasket thicknesses, with this particular gasket having a compressed thickness of 0.036 inches.

This head gasket fits a wide range of Ford vehicles, including classic models like the AC Shelby Cobra and Ford Bronco, as well as Ford Econoline vans and trucks. It's a well-built option for rebuilding or repairing your engine's top end.
