Cometic GM L18 Vortec 8100 Gen-VII Big Block V8 .080in MLS Cylinder Head Gasket - 4.280in Bore - LHS

When you're rebuilding the top end of your GM L18 Vortec 8100 Gen-VII Big Block V8, you'll want a head gasket that can handle the pressure. This Cometic Multi-Layer Steel (MLS) head gasket is built for those demanding applications. It's designed to provide a strong seal between your cylinder head and engine block, crucial for maintaining compression and preventing leaks.

This gasket is constructed from multiple layers of stainless steel, giving it 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°F (250°C) and works well with different block and head materials, including aluminum and cast iron. The compressed thickness of this gasket is 0.098 inches, and it features a 4.280-inch bore, making it suitable for engines with that specific cylinder bore size. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying installation.

This gasket fits a range of heavy-duty GM trucks and SUVs, including models like the Chevrolet Silverado 2500 HD and GMC Sierra 3500. It's a solid option for anyone looking for a well-built gasket for their Vortec 8100 engine.
