Cometic GM LS Gen-3/4 Small Block V8 .092in MLS Cylinder Head Gasket - 3.910in Bore

Cometic Gasket is a well-known name for making solid sealing solutions, especially for high-output engines. This Multi-Layer Steel (MLS) head gasket is built for GM LS Gen-3 and Gen-4 small block V8 engines. It has a bore size of 3.910 inches and an installed thickness of .092 inches, making it a popular choice for rebuilding or upgrading these popular V8s, found in vehicles like the Chevrolet Silverado and GMC Sierra trucks, as well as the Chevrolet Corvette.

This gasket is constructed with multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal even in demanding conditions. The center layer is uncoated stainless steel, and its thickness can be varied to meet different engine build requirements. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying installation for both aluminum-to-aluminum and aluminum-to-cast iron block setups.
