About this part

Product Details

What you get here is a Cometic Multi-Layer Steel (MLS) head gasket designed for Chevrolet Gen-1 Small Block V8 engines. This gasket is specifically built with a 4.165-inch bore and a compressed thickness of 0.040 inches, making it a solid option for many classic V8 builds. It's engineered to handle the demands of high-output engines and fits a wide range of vehicles from the early 80s, including models like the Chevrolet C10 and Camaro, as well as Buick Regal and GMC C1500 trucks.

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. This coating is applied to both sides and is designed to work well with different head and block materials, like aluminum to aluminum or aluminum to cast iron, without needing extra sealants. The center layer is uncoated stainless steel, allowing for precise thickness control.

You'll also find that this gasket includes steam holes, which help manage heat and pressure within the engine. The valve pocketed bore is another detail that ensures a good seal around the combustion chamber. This is a well-built part that aims to provide reliable sealing performance for your engine rebuild.
