Cometic GM LGD/LZ4/LZ8/LZ9/LZE/LZG High Value .051in MLS Cylinder Head Gasket - 101mm Bore - RHS

When you're rebuilding the top end of your GM LGD, LZ4, LZ8, LZ9, LZE, or LZG engine, getting the head gasket right is crucial for sealing combustion pressure. This Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of higher output engines, offering a solid seal without needing extra sealants.

This gasket is constructed from multiple layers of stainless steel, which gives it strength and helps it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and different surface finishes, making it suitable for pairings like aluminum heads to cast iron blocks. The compressed thickness is .051 inches, and it has a 101mm bore, designed to fit a range of GM vehicles including the Chevrolet Impala, Pontiac G6, and Buick Rendezvous.
