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

This product is a right-side Multi-Layer Steel (MLS) cylinder head gasket for GM L18 Vortec 8100 Gen-VII Big Block V8 engines. It features a compressed operating thickness of .089 inches and a bore size of 4.450 inches. This gasket is designed to provide maximum sealing performance for high-output engines and fits a range of heavy-duty trucks and SUVs, including models like the Chevrolet Silverado 2500 HD and GMC Yukon XL 2500.

Cometic MLS head gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482°F (250°C). This construction makes them suitable for use with both aluminum and cast iron blocks, and they don't require any additional sealants for installation. The center layer is uncoated stainless steel and can be varied to achieve different thickness requirements.
