Cometic Pontiac 400/428/455 V8 .036in MLS Cylinder Head Gasket - 4.410in Bore

This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket, specifically made for Pontiac 400, 428, and 455 cubic inch V8 engines. It features a 4.410 inch bore and a compressed thickness of 0.036 inches. This gasket is designed to provide a strong seal for a wide range of classic GM vehicles, including models like the Pontiac Firebird, GTO, and Grand Prix from the late 60s through the late 70s.

Cometic builds these MLS 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 tough sealing conditions and different surface finishes, making it suitable for both aluminum and cast iron block combinations. Because they're made this way, these gaskets don't require any additional sealants, simplifying installation. The center layer is stainless steel and can be varied in thickness to meet different engine build needs.
