Cometic GM 3.1L 60 Deg V6 L82 91mm Bore .040in MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an outer layer coated with Viton rubber. This construction is designed to handle the demands of high-output engines and provides excellent sealing performance without needing additional sealants. The Viton coating, heat resistant up to 482°F (250°C), is tough enough for various harsh sealing environments and surface finishes, making it suitable for applications with aluminum heads on either aluminum or cast iron blocks. The center layer is uncoated stainless steel, allowing for precise thickness control, and this particular gasket has a compressed operating thickness of 0.036 inches with a 91mm bore, specifically sized at .040 inches for your engine build.

MLS gaskets offer increased strength due to their layered stainless steel construction, which also allows them to rebound and resist corrosion. This makes them a solid choice for engines that push the limits. This gasket fits a range of GM vehicles, including models like the Buick Century, Chevrolet Lumina, and Pontiac Grand Am, ensuring a proper seal for your engine's top end.
