Cometic GM L18 Vortec 8100 Gen-VII Big Block V8 .089in MLS Cylinder Head Gasket - 4.450in Bore - LHS

This product is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for the GM L18 Vortec 8100 Gen-VII Big Block V8 engine. It has a compressed thickness of .089 inches and a bore size of 4.450 inches, and this specific gasket is for the left-hand side of the engine. These gaskets are built to handle the demands of high-output engines and are suitable for applications with aluminum heads on either aluminum or cast iron blocks.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a strong seal even under tough conditions. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, making these gaskets adaptable. Because they are MLS, they don't require any additional sealants for installation.

This gasket fits a range of heavy-duty Chevrolet and GMC trucks and SUVs, including models like the Chevrolet Silverado 2500 HD and GMC Sierra 3500 from 2001 through 2007. It's a well-built component for rebuilding or repairing your Vortec 8100 engine.
