Product Details
If you're rebuilding the top end of your GM L18 Vortec 8100 Gen-VII Big Block V8, a solid set of head gaskets is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these powerful engines, ensuring a reliable seal between your cylinder heads and block.
Cometic uses multiple layers of stainless steel for increased strength and corrosion resistance, which also helps the gasket rebound and maintain its seal. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes, making it suitable for both aluminum and cast iron blocks. With a compressed thickness of .089 inches and a 4.280-inch bore, this gasket is designed for a precise fit on a range of GM trucks and SUVs like the Chevrolet Silverado 2500 HD and GMC Sierra 3500.
These MLS gaskets don't require any additional sealants, simplifying the installation process. They are a popular choice for high-output applications where a dependable seal is paramount.
