Cometic Pontiac 400/428/455 V8 .080in MLS Cylinder Head Gasket - 4.160in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built for Pontiac V8 engines like the 400, 428, and 455. You get one gasket, measuring .080 inches thick with a 4.160-inch bore, designed to seal the combustion chamber and coolant passages between your cylinder heads and engine block. It's a well-built component for rebuilding or upgrading your engine.

Cometic uses 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 works well with both aluminum and cast iron blocks, even when paired with aluminum heads. This construction means the gasket doesn't need any extra sealants and is designed to handle the high pressures found in performance engines. The center layer can be varied to achieve different thicknesses, and in this case, it's set at .080 inches to suit specific engine builds.

This gasket fits a range of Pontiac, Buick, and Oldsmobile vehicles from the late 60s through the late 70s, including models like the Pontiac Firebird, Grand Prix, and Catalina. It's a solid option if you're working on a performance Pontiac V8.
