Cometic GM LS Gen-3/4 Small Block V8 .060in MLS Cylinder Head Gasket - 3.810in Bore

If you're working on a GM LS Gen-3 or Gen-4 small block V8, this Cometic Multi-Layer Steel (MLS) head gasket is built to seal up your cylinders. It's designed with a 3.810-inch bore and is .060 inches undersize, which is important for specific engine builds where precise clearance is needed. This gasket is a solid option for a wide range of GM trucks, SUVs, and cars from the early 2000s through the early 2010s, including popular models like the Chevrolet Silverado 1500 and GMC Yukon.

What sets this gasket apart is its HP shim technology. This feature helps increase the clamping force around the combustion chamber, which is especially beneficial for open deck blocks. This improved sealability helps prevent leaks and ensures your engine runs efficiently. The outer layers of the gasket are embossed and coated with Viton, a high-performance fluoroelastomer known for its resistance to heat and fluids, further enhancing its sealing capabilities and durability.
