Product Details
If you're working on a GM LT1 or LT4 Gen-2 small block V8, specifically models from 1992 through 1997, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the job. It's designed with a 4.040 inch bore and a compressed operating thickness of 0.070 inches, making it a solid choice for rebuilding or replacing head gaskets on a range of vehicles like the Chevrolet Corvette, Camaro, and Pontiac Firebird.
This gasket is constructed from 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 good seal even in demanding conditions. Because it's an MLS gasket, it doesn't require any additional sealants and works well with both aluminum and cast iron blocks, providing a reliable seal that can withstand the forces created by different metal combinations.
