Cometic GM L18 Vortec 8100 Gen-VII Big Block V8 .051in MLS Cylinder Head Gasket - 4.450in Bore - LHS

This is the Cometic Multi-Layer Steel (MLS) cylinder head gasket for the GM L18 Vortec 8100 Gen-VII Big Block V8 engine. It's designed with a 4.450-inch bore and a compressed thickness of 0.051 inches, specifically for the left-hand side of the engine. This gasket fits a range of heavy-duty trucks and SUVs, including models like the Chevrolet Silverado 2500 HD and GMC Sierra 3500, from the early 2000s up to 2007.

Cometic builds these gaskets using multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes. This construction means the gasket seals effectively without needing any additional sealants, making it suitable for applications with both aluminum and cast iron blocks.
