Cometic GM LS Gen-3/4 Small Block V8 .060in MLS Cylinder Head Gasket - 4.000in Bore

Cometic Gasket is a well-known name for making solid engine sealing solutions. This Multi-Layer Steel (MLS) head gasket is built for GM LS Gen-3 and Gen-4 small block V8 engines, specifically designed for a 4.000-inch bore and is .060 inches undersize. These gaskets are ideal for high-output engines where reliable sealing is critical, and they don't require any additional sealants.

The construction uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with different engine materials like aluminum heads on cast iron blocks. The center layer is stainless steel and can be varied to achieve different compressed thicknesses, with this particular gasket having a compressed thickness of 0.036 inches. This design helps manage the shearing forces that can occur between dissimilar metals.

This gasket fits a wide range of vehicles, including popular models like the Chevrolet Silverado 1500, Chevrolet Corvette, and Cadillac CTS. It's a solid option for rebuilding or upgrading your LS engine.
