Cometic Ford 289/302/351 4.030 inch Bore .045 inch MLS Head Gasket (Non SVO)

If you're rebuilding the top end of your Ford Windsor V8, getting the head gaskets right is crucial for a solid seal. This Multi-Layer Steel (MLS) head gasket from Cometic is built for engines with a 4.030 inch bore and a compressed thickness of 0.045 inches. It's designed to handle the demands of higher output engines, ensuring a reliable seal without needing extra sealants.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance, which also allows the gasket to rebound and maintain its seal. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction makes them suitable for mating aluminum heads to either aluminum or cast iron blocks, as they can manage the shearing forces that can occur between different metals. The center layer is stainless steel, and its thickness can be varied to achieve different compressed gasket thicknesses, like the 0.045 inches on this specific gasket.

This gasket fits a wide range of Ford vehicles, including classic Broncos, F-Series trucks, and many other V8 applications from the 60s through the 90s. It's a well-built option for anyone looking for a dependable seal during their engine rebuild.
