Cometic GM L18 Vortec 8100 Gen-VII Big Block V8 .080in MLS Cylinder Head Gasket - 4.350in Bore - LHS

Cometic Gasket is well-known for making solid sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's built for GM L18 Vortec 8100 Gen-VII Big Block V8 engines, specifically designed to handle the demands of these powerful motors. This gasket is a crucial part of your engine's top end, ensuring a tight seal between the cylinder head and the engine block to maintain compression and prevent coolant or oil leaks.

What makes this gasket stand out is its construction. It's made from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, making it ideal for sealing in harsh engine environments. The compressed thickness is 0.098 inches, and this particular gasket has a 0.080-inch thickness and a 4.350-inch bore, designed to fit specific engine configurations. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying installation.

This gasket fits a range of heavy-duty GM vehicles, including models like the Chevrolet Suburban 2500 and GMC Sierra 2500 HD. It's a well-built component that helps ensure your engine runs smoothly and reliably.
