What is the purpose of the Viton coating on the outer layers?

The Viton coating on the outer layers is a heat-resistant rubber material designed to handle harsh sealing environments and high temperatures, up to 482 degrees Fahrenheit. It helps ensure a reliable seal between the cylinder head and the engine block.

What is the benefit of the multi-layer steel construction?

The multi-layer steel construction gives the gasket increased strength and the ability to rebound, which helps it withstand the demands of high-output engines. It also provides resistance to corrosion.

About this part

Product Details

Cometic Gasket is well-known for making robust multi-layer steel (MLS) head gaskets that handle high-output engines. This particular gasket is built for GM Gen-V/VI Big Block V8 engines and features a 4.630-inch bore with a compressed thickness of 0.036 inches. It's designed to provide maximum sealing performance without needing any extra sealants, making the job straightforward.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This makes it suitable for use with both aluminum and cast iron blocks, and it can handle the shearing forces that can occur between different metals. The center layer is uncoated stainless steel, allowing for variations in thickness to meet specific engine needs.

This gasket fits a wide range of GM trucks and vans from the early 90s through the late 90s and early 2000s, including models like the Chevrolet C1500 and GMC C2500 Suburban. It's a solid option for rebuilding or repairing your engine's top end.
