Cometic GM L18 Vortec 8100 Gen-VII Big Block V8 .045in MLS Cylinder Head Gasket - 4.350in Bore - LHS

If you're working on a GM L18 Vortec 8100 Gen-VII Big Block V8, this Cometic Multi-Layer Steel (MLS) cylinder head gasket is built to handle the demands of those powerful engines. This gasket is specifically for the left-hand side and has a compressed thickness of 0.045 inches with a 4.350-inch bore, designed to seal the combustion chamber effectively.

Cometic's MLS gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle high temperatures and harsh sealing environments. This construction means the gasket requires no additional sealants and is suitable for applications with aluminum heads and either aluminum or cast iron blocks, as it can manage the shearing forces between different metals.

This gasket is a solid option for rebuilding or repairing engines in a range of vehicles, including the Chevrolet Silverado 2500 HD and GMC Yukon XL 2500, among others. Its robust multi-layer design ensures a reliable seal under demanding conditions.
