What makes this gasket suitable for aftermarket heads?

This gasket is designed for aftermarket heads and features undersized water ports. This allows for customization to match your specific head and block configuration, ensuring a proper seal.

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

The Viton coating is a heat-resistant rubber material that meets the demands of harsh sealing environments. It helps create a reliable seal against various surface finishes and load conditions, even at high temperatures.

Does this gasket require any additional sealants?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance on their own and do not require any additional sealants. This simplifies the installation process.

About this part

Product Details

When you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, you need a head gasket that can handle the pressure. This Multi-Layer Steel (MLS) gasket from Cometic is built for that job. It's designed to provide maximum sealing performance, especially for engines that are making more power than stock. You get the gasket itself, which is constructed from multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes.

The compressed operating thickness of this gasket is 0.075 inches, and it has a 4.125-inch bore. It's specifically noted as being suitable for aftermarket heads, with undersized water ports that allow for customization to your specific setup. Because it's an MLS design, it requires no additional sealants, making installation a bit more straightforward. These gaskets are a solid option whether you're pairing aluminum heads with an aluminum block or aluminum heads with a cast iron block, as they can handle the shearing forces that can occur between different metals.

This gasket fits a wide range of Chevrolet and GMC trucks, cars, and SUVs from the early to mid-1980s, including models like the Chevrolet C10 and GMC C1500. It's also a good choice for performance applications like the Chevrolet Camaro and Corvette.
