Cometic Ford 289/302/351 4.100 inch Bore .051 inch MLS Head Gasket (Non SVO)

If you're rebuilding the top end of your Ford Windsor V8, like a 289, 302, or 351, getting the head gasket right is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures of modern, high-output engines without needing any extra sealants. It's designed to work well whether you're mating aluminum heads to an aluminum block or to a cast iron block, resisting the shearing forces that can occur between different metals.

Cometic builds these gaskets with multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and seal effectively even on varied surface finishes. The center layer is stainless steel, and its thickness can be adjusted to meet different requirements, with this specific gasket having a compressed operating thickness of 0.051 inches and a bore size of 4.100 inches. This well-built gasket is a popular choice for a wide range of Ford vehicles, including Broncos, Econoline vans, and classic Mustangs.
