Cometic GM L42/L61 Gen-1/2 ECOTEC .045in MLS Cylinder Head Gasket - 89mm Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built for GM L42/L61 Gen-1/2 ECOTEC engines with an 89mm bore. It has a compressed thickness of .045 inches, designed to provide a strong seal for performance applications. This gasket is suitable for use with both aluminum and cast iron blocks, and it can handle the stresses that come from mating different metals together.

The gasket is constructed from multiple layers of stainless steel, which gives it 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. This coating helps to create a reliable seal without the need for additional sealants, even under demanding conditions. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .045 inches found in this specific gasket.

This gasket fits a range of vehicles, including models like the Chevrolet Cavalier, Cobalt, and Pontiac Sunfire. It's a well-built component for rebuilding or upgrading your ECOTEC engine.
