Cometic GM LT1/LT4 Gen-2 Small Block V8 .056in MLS Cylinder Head Gasket - 4.040in Bore

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s designed for GM LT1/LT4 Gen-2 Small Block V8 engines, fitting a range of vehicles like the Chevrolet Camaro, Pontiac Firebird, and Chevrolet Corvette from the mid-90s. If you're rebuilding the top end of one of these popular V8s, a reliable head gasket is crucial for keeping compression where it belongs and preventing coolant and oil leaks.

This gasket uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes, meaning you don't need extra sealants. The center layer is stainless steel and can be varied in thickness; in this case, it's set to provide a 0.056-inch compressed thickness with a 4.040-inch bore, ideal for many performance applications. These MLS gaskets are a solid choice whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as they can handle the different expansion rates.
