Product Details
If you're rebuilding the top end of your 1992-1996 GM LT1 or LT4 small block V8, a solid set of head gaskets is crucial for sealing the combustion chamber and preventing coolant and oil leaks. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these performance-oriented engines.
Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. 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 head and block materials, including aluminum to cast iron. This gasket has a compressed thickness of 0.075 inches and is designed for a 4.100-inch bore, fitting a range of GM vehicles like the Chevrolet Camaro, Corvette, and Pontiac Firebird.
Because these are MLS gaskets, they don't require any additional sealants, making installation more straightforward. They are a well-built option for ensuring a reliable seal in your engine build.
