Product Details
This product is a right-side, Multi-Layer Steel (MLS) cylinder head gasket from Cometic, designed for Buick 3800 Series II and III V6 engines. It features a compressed operating thickness of 0.092 inches and a bore size of 3.840 inches. This gasket is built to handle the demands of high-output engines and is suitable for use with both aluminum and cast iron blocks, as well as aluminum heads. It fits a wide range of vehicles, including models like the Buick LeSabre, Pontiac Grand Prix, and Chevrolet Camaro from the mid-90s to early 2000s.
The construction of this MLS gasket involves multiple layers of stainless steel, which provides increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit. This coating is designed to perform well in harsh sealing environments and under various load conditions. The center shim layer is uncoated stainless steel and can be varied to achieve different thickness requirements, ensuring a precise fit for your engine build. Because it's an MLS gasket, it doesn't require any additional sealants for installation.
