Cometic GM LS Gen-3/4 Small Block V8 .140in MLS Cylinder Head Gasket - 4.100in Bore

If you're rebuilding the top end of your GM LS Gen-3/4 small block V8, a reliable head gasket is crucial for sealing combustion pressure and coolant. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring a solid seal between your cylinder heads and block.

Cometic uses multiple layers of stainless steel for increased strength and rebound resistance, which helps prevent leaks even with dissimilar metals like aluminum heads and cast iron blocks. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F and works well in tough sealing environments. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .140 inch compressed thickness on this particular gasket, which is designed for a 4.100 inch bore. These gaskets are designed to seal without needing any additional sealants.

This gasket fits a wide range of GM vehicles, including popular models like the Chevrolet Silverado, Corvette, and Cadillac CTS. It's a well-built option for anyone looking to ensure a strong seal during their engine build.
