Cometic GM LS1 (w/M.I.D. Sleeves) 4.165 inch Bore .060 inch MLS-5 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 engines, featuring a 4.165 inch bore and a compressed operating thickness of 0.060 inches. It's designed to handle the demands of high-output applications, fitting a range of vehicles like the Chevrolet Camaro, Corvette, and Pontiac GTO.

This gasket is constructed from multiple layers of stainless steel, which gives it strength and helps it resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is also stainless steel and can be varied to achieve different thicknesses, like the 0.060 inch compression thickness on this specific gasket. It also includes Darton MID Sleeves, which are designed to work with specific block configurations. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward.
