Cometic Ford 302/351W Windsor V8 .098in MLS Cylinder Head Gasket - 4.100in Bore - SVO/Yates - RHS

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Ford 302 and 351 Windsor V8 engines. It features a 4.100-inch bore and a compressed thickness of .098 inches, making it suitable for a wide range of Ford vehicles like the Bronco, Econoline vans, and Pantera, as well as custom builds using SVO/Yates or RHS blocks. MLS gaskets are essential for high-output engines because they offer superior sealing performance compared to traditional composite gaskets, especially when dealing with the stresses of increased cylinder pressures and temperatures.

Cometic builds these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and provides a reliable seal against various fluids and surface finishes. The center shim layer can be varied to achieve different thicknesses, and in this case, it's set to provide a .098-inch compressed gasket thickness. These gaskets are designed to work well with both aluminum and cast iron blocks and heads, and they don't require any additional sealants, simplifying the installation process.
