Cometic Chevy BB 4.63in Bore .040 inch MLS 396/402/427/454 Head Gasket

When you're rebuilding a big block Chevy engine, getting the right head gasket is crucial for sealing power. This Multi-Layer Steel (MLS) gasket from Cometic is built for those high-output applications, designed to handle the demands of engines like the 396, 402, 427, and 454. It features a compressed operating thickness of .040 inches, ensuring a precise fit and seal.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes, making it suitable for both aluminum and cast iron blocks. This construction means you don't need additional sealants for installation, simplifying the process and providing a reliable seal right out of the box. The center layer is also stainless steel, allowing for variation in thickness to meet specific engine build needs.

This gasket fits a range of Chevrolet and GMC big block applications from the early 90s through the early 2000s, including models like the C1500, K2500 Suburban, and G3500. It's a solid option for anyone looking for a well-built head gasket for their performance-oriented engine build.
