Cometic Pontiac 400/428/455 V8 .080in MLS Cylinder Head Gasket - 4.410in Bore

This product is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Pontiac 400, 428, and 455 V8 engines. It features a compressed operating thickness of 0.080 inches and a bore size of 4.410 inches. This gasket is built to handle the demands of high-output engines and fits a range of vehicles, including models like the Pontiac Firebird, GTO, and Catalina from the late 1960s through the late 1970s.

Cometic MLS head gaskets are constructed from multiple layers of stainless steel, offering increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can withstand temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal in harsh conditions. These gaskets are suitable for use with both aluminum and cast iron blocks, and they do not require any additional sealants for installation, making them a straightforward choice for engine rebuilds or upgrades.
