Cometic Buick Big Block V8 .051in MLS Cylinder Head Gasket - 4.400in Bore

Cometic Gasket is well-known for making solid sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s built for Buick Big Block V8 engines and features a 4.400-inch bore with a compressed thickness of 0.051 inches. This gasket is designed to handle the demands of high-output engines, ensuring a reliable seal without needing additional sealants.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This makes it suitable for sealing between aluminum heads and either aluminum or cast iron blocks, as it can manage the shearing forces that arise from these material combinations. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.051-inch compressed thickness on this particular gasket.

This gasket fits a range of Buick vehicles, including models like the Electra, Riviera, and Skylark from the late 1960s and early 1970s. It's a well-built component for rebuilding or repairing your engine's top end.
