Cometic Buick Big Block V8 .072in MLS Cylinder Head Gasket - 4.385in Bore

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's built for Buick Big Block V8 engines and features a 4.385-inch bore with a compressed thickness of 0.098 inches. This gasket is designed to handle the demands of high-output engines, offering maximum sealing performance without needing additional sealants. It's a solid choice for applications using aluminum heads with either aluminum or cast iron blocks, as the multi-layer steel construction can manage the shearing forces that arise between different metals.

The strength of this MLS gasket comes from its multiple layers of stainless steel, which also helps it resist corrosion and maintain its shape. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This makes it suitable for harsh sealing environments and varying surface finishes. The center layer is uncoated stainless steel, and its thickness can be varied to meet different sealing requirements, ensuring a precise fit for your engine build. This gasket fits a range of Buick vehicles from the late 60s to the mid-70s, including models like the Electra, Riviera, and LeSabre.
