Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on a GM L18 Vortec 8100 Gen-VII Big Block V8 engine, this gasket is designed to provide a strong seal between your cylinder head and block. It's built to handle the demands of high-output engines, ensuring reliable performance for your truck or SUV.

This gasket is constructed from multiple layers of stainless steel, which gives 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 surface finishes. The compressed thickness of this gasket is 0.098 inches, and it features a 4.350-inch bore, making it suitable for specific engine builds. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process.

This head gasket fits a variety of GM vehicles, including models like the Chevrolet Avalanche 2500, Chevrolet Silverado 2500 HD, and GMC Sierra 3500. It's a solid option for rebuilding or repairing the top end of these big block V8 engines.
