Cometic Ford 289/302/351 4.080 inch Bore .066 inch MLS-5 Head Gasket (Non SVO)

Cometic Gasket has a solid reputation for making well-built engine components, and this Multi-Layer Steel (MLS) head gasket is a great example. It’s built for Ford Windsor V8 engines with a 4.080-inch bore, designed to handle the demands of higher output applications. This gasket is a direct replacement for non-SVO applications and is suitable for both aluminum heads on aluminum blocks and aluminum heads on cast iron blocks, as it can handle the different expansion rates between those materials.

The construction here is key. It uses multiple layers of stainless steel for increased strength and resistance to corrosion, with embossed outer layers that are coated on both sides with Viton, a heat-resistant rubber material. This Viton coating is designed to seal effectively in harsh environments and on various surface finishes, meaning you won't need to use any extra sealants. The compressed operating thickness is .066 inches, and the center layer is stainless steel, which can be varied to achieve different thicknesses. This gasket fits a wide range of vehicles, including classic Ford Broncos, Econoline vans, and even some De Tomaso models.
