Cometic Ford 289/302/351 4.200 inch Bore .098 inch MLS-5 Head Gasket (Non SVO)

Starting with a compressed thickness of 0.098 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for serious sealing. It's specifically designed for Ford Windsor V8 engines with a 4.200 inch bore, and it's important to note this is the non-SVO version. These gaskets are a popular choice for high-output engines because they offer maximum sealing performance right out of the box, meaning you don't need to mess with sealants.

The construction here is pretty solid: multiple layers of stainless steel give it 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 degrees Fahrenheit. This makes them ideal for pairing aluminum heads with either aluminum or cast iron blocks, as they can handle the different expansion rates and shearing forces between those materials. The center layer is stainless steel and can be varied in thickness to meet different build requirements.

This gasket fits a wide range of classic Ford vehicles, including models like the Ford Bronco, Ford E-Series vans, and even older AC Shelby Cobras. It's a well-built component designed to keep your engine sealed tight under demanding conditions.
