Cometic GM LS1 SB 4.190in Bore .070in MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with a 4.190-inch bore and a .070-inch thickness, making it a solid choice for GM LS Gen-3 and Gen-4 small block V8 engines. It's designed to handle the demands of these popular V8s, including models like the Chevrolet Corvette, Camaro, and Silverado. The gasket's construction is key to maintaining a strong seal between your engine block and cylinder heads.

What sets this gasket apart is its HP shim technology. This advanced feature increases the clamping force around the combustion chamber, which is especially important for open deck blocks. This improved sealability helps prevent leaks and ensures consistent engine performance. Additionally, both sides of the gasket are coated with Viton, a high-performance fluoroelastomer that offers excellent resistance to heat and oil, further enhancing its sealing capabilities and durability in demanding engine environments.

When rebuilding or repairing your GM LS engine, choosing the right head gasket is crucial for long-term reliability. This Cometic gasket offers a well-built solution designed to maintain integrity under pressure. Always refer to your vehicle's service manual for specific installation procedures and torque specifications to ensure a proper seal.
