Cometic GM LS1 (w/M.I.D. Sleeves) 4.165 inch Bore .030 inch MLS Head Gasket

Cometic Gasket is known for making well-built sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s built for GM LS engines, specifically designed for a 4.165 inch bore and a compressed thickness of .030 inch, and it comes with Darton MID sleeves already integrated. This gasket is a solid option for anyone rebuilding or modifying their LS engine, whether you're pairing aluminum heads with an aluminum block or cast iron block.

What makes these MLS gaskets stand out is their construction. They use multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and works well in tough sealing environments. This coating, along with the embossed layers, helps ensure a maximum seal without needing any extra sealants, making installation more straightforward. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .030 inch on this particular gasket.

This gasket fits a wide range of GM vehicles, including models like the Chevrolet Camaro, Corvette, and Pontiac GTO. It's designed to handle the demands of high-output engines, providing a reliable seal that can withstand significant shearing forces between different block and head materials.
