Cometic GM LS1 SB 4.100in Bore .051in MLS-5 Head Gasket

When you're rebuilding the top end of your GM LS Gen-3 or Gen-4 V8 engine, getting the cylinder head gaskets seated properly is critical for sealing combustion pressures and coolant. This Cometic MLS-5 head gasket is designed for that job, fitting a wide range of popular GM vehicles like the Chevrolet Camaro, Corvette, and Silverado trucks.

This gasket is constructed with multiple layers of stainless steel, which gives it strength and helps it resist corrosion and rebound under pressure. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and temperatures up to 482°F. The gasket has a bore size of 4.100 inches and a thickness of .051 inches, making it suitable for many stock and modified LS engine builds.
