Cometic GM LS1 SB 4.160 inch Bore .051 inch MLS Head Gasket

Cometic Gasket is well-known for making solid sealing solutions for performance engines. This Multi-Layer Steel (MLS) head gasket is built for GM LS Gen-3 and Gen-4 small block V8 engines, including popular models like the Chevrolet Corvette, Camaro, and Silverado trucks. It's designed to handle the demands of high-output applications, ensuring a reliable seal between your cylinder heads and engine block.

This gasket features multiple layers of stainless steel for 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 and sealing environments. The compressed thickness is a precise 0.051 inches, with a bore size of 4.160 inches, making it suitable for a variety of LS engine builds. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying installation.

This gasket is a good choice for both aluminum-to-aluminum and aluminum-to-cast iron block configurations, as it can manage the stresses that arise from dissimilar metals. It fits a wide range of vehicles, from performance cars like the Cadillac CTS to work trucks like the Chevrolet Express vans.
