Cometic Ford 302/351W Windsor V8 .040in MLS Cylinder Head Gasket - 4.210in Bore - SVO/Yates

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket specifically made for Ford 302 and 351 Windsor V8 engines. It's designed with a 4.210 inch bore and is 0.040 inches undersize, intended for applications like SVO/Yates racing blocks. MLS gaskets are a popular choice for high-output engines because they offer excellent sealing without needing extra sealants, and they handle the stresses between aluminum and cast iron blocks well.

Cometic builds these gaskets with multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes. The center layer is stainless steel and can be varied in thickness; in this case, it's set to achieve a compressed operating thickness of 0.036 inches, which is ideal for many performance builds. This construction helps prevent leaks and ensures consistent performance under demanding conditions.

This gasket fits a wide variety of Ford vehicles, including the Bronco, E-Series vans, and F-Series trucks, as well as some Bricklin and DeTomaso models from the 70s and 80s. Always double-check your specific engine and bore size to ensure this is the correct gasket for your build.
