Product Details
This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Ford 302 and 351 Windsor V8 engines. It has a bore size of 4.030 inches and a compressed thickness of .140 inches. This gasket is built to handle the demands of high-output engines and fits a wide range of Ford vehicles, including models like the Ford Bronco, E-Series vans, and Country Squire wagons from various years.
Cometic's MLS gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes. This construction means the gasket seals effectively without needing additional sealants, making it suitable for combinations of aluminum and cast iron blocks and heads. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .140 inches on this specific gasket.
Because these gaskets are well-built with multiple layers and a specialized coating, they are a solid option for rebuilding or upgrading your Ford Windsor V8. They are designed to maintain a strong seal under demanding conditions.
