Cometic Ford 289/302/351 4.200 inch Bore .066 inch MLS-5 Head Gasket (Non SVO)

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring an outer coating of Viton rubber. The Viton coating is heat resistant up to 482 degrees Fahrenheit, making it suitable for harsh sealing environments and various surface finishes. With a compressed operating thickness of 0.066 inches and a bore size of 4.200 inches, this gasket is specifically designed for Ford 289, 302, and 351 Windsor V8 engines that are not SVO (Special Vehicle Operations) variants.

MLS gaskets are a solid choice for modern, high-output engines because they offer maximum sealing performance without needing additional sealants. They work well with both aluminum heads on aluminum blocks and aluminum heads on cast iron blocks, as they can handle the shearing forces that can occur between different metals. The layered stainless steel construction provides increased strength and the ability to rebound, while also resisting corrosion. The center shim layer is stainless steel and can be varied to achieve different thickness requirements, offering flexibility for engine builds.

This gasket fits a wide range of Ford V8 vehicles, including classic Broncos, F-Series trucks, and Econoline vans from various years. It's a well-built component for anyone rebuilding or refreshing their Ford Windsor V8 engine.
