Cometic GM LS Gen-3/4 Small Block V8 .045in MLS Cylinder Head Gasket - 4.160in Bore

When you're rebuilding the top end of your GM LS Gen-3 or Gen-4 small block V8, getting the cylinder head gaskets seated correctly is crucial for a good seal. This Cometic Multi-Layer Steel (MLS) head gasket is built for that job. It's designed to handle the high output these engines are known for, providing a strong seal without needing extra sealants.

These gaskets are constructed from multiple layers of stainless steel, which gives them strength and helps them 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 them suitable for aluminum heads on either aluminum or cast iron blocks. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses; this particular gasket has a compressed operating thickness of 0.045 inches and a bore size of 4.160 inches, which is a common size for many LS engine builds.

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