Cometic GM LS Gen-3/4 Small Block V8 .120in MLS Cylinder Head Gasket - 4.100in Bore

If you're rebuilding the top end of your GM LS Gen-3 or Gen-4 small block V8, getting the cylinder head gaskets seated right is crucial for a leak-free seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these popular engines, whether they're in a performance build or a daily driver.

Cometic uses multiple layers of stainless steel for strength and rebound, which helps prevent corrosion and maintain sealing pressure over time. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482°F (250°C) and works well with different surface finishes on both aluminum and cast iron blocks. This gasket has a compressed thickness of .120 inches and a bore size of 4.100 inches, designed to match the specifications of many LS engines. Because it's an MLS design, it doesn't require any additional sealants, making installation more straightforward.

This gasket is a solid option for a wide range of GM vehicles, including models like the Chevrolet Silverado 1500, Cadillac CTS, and Chevrolet Camaro. It's designed to provide reliable sealing for your engine's combustion chambers.
