Cometic Ford 351 Cleveland 4.100 inch Bore .040 inch MLS Head Gasket

Starting with a compressed operating thickness of 0.040 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing. It's specifically designed for Ford 351 Cleveland engines with a 4.100 inch bore, fitting a wide range of vehicles like the Ford F-150, Mercury Cougar, and De Tomaso Pantera from various years.

The multi-layer stainless steel construction offers increased strength and resistance to corrosion, while the outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This combination ensures a reliable seal even in high-output engine conditions, and the gasket doesn't require any additional sealants. The center layer is uncoated stainless steel, allowing for precise thickness control.

These MLS gaskets are a solid choice for applications using aluminum heads with either aluminum or cast iron blocks, as they can effectively manage the shearing forces that can occur between different metals.
