Cometic GM LS1 SB 4.160 inch Bore .070 inch MLS Head Gasket

When you're rebuilding the top end of your GM LS Gen-3 or Gen-4 V8, you need a head gasket that can handle the job. This Cometic MLS (Multi-Layer Steel) head gasket is built for that purpose. It features a 4.160 inch bore and a .070 inch thickness, making it suitable for a wide range of GM LS engines, including those found in vehicles like the Chevrolet Corvette, Cadillac CTS, and Chevrolet Silverado.

What sets this gasket apart is its HP shim technology. This design increases the clamping force around the combustion chamber, which is especially helpful for open deck blocks. This improved sealability helps prevent leaks and ensures your engine runs smoothly. Plus, the gasket is coated on both sides with Viton, a high-performance fluoroelastomer that offers excellent resistance to heat and chemicals, further enhancing its sealing capabilities.
