Cometic GM Gen-V/VI Big Block V8 .030in MLS Cylinder Head Gasket - 4.540in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built for GM Gen-V/VI Big Block V8 engines and comes with a 4.540-inch bore size, specifically sized at 0.030 inches compressed thickness. It's designed to provide a strong seal for high-output applications, meaning it can handle the extra pressure and heat these engines often generate. You get the gasket itself, ready to install.

What makes these gaskets stand out is their construction. They're made from multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This combination is great for sealing between aluminum heads and either aluminum or cast iron blocks, as it can manage the different expansion rates and shearing forces. Because they're MLS, they don't need any extra sealants, making installation a bit more straightforward.

This gasket fits a wide range of Chevrolet and GMC trucks from the early to mid-90s, including models like the C1500 and K2500 Suburban. It's a solid option when you're rebuilding the top end of your engine and need a reliable seal.
