Cometic GM 1998-2003 L43/LN2 Gen-2 122 .045in MLS Cylinder Head Gasket - 90mm Bore

If you're rebuilding the top end of your 1994-2003 Chevrolet S10, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice. It's designed specifically for the GM L43/LN2 Gen-2 122 engine, with a 90mm bore and a thickness of .045 inches. This gasket is built to handle the demands of modern engines, providing a reliable seal without needing extra sealants.

Cometic constructs these MLS gaskets from multiple layers of stainless steel. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This construction not only offers increased strength to resist shearing forces between different block and head materials (like aluminum to cast iron), but the stainless steel also helps prevent corrosion and allows the gasket to rebound effectively. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .045 inches on this particular gasket.
