What makes this gasket different from a standard composite head gasket?

This gasket is made from copper, which is more malleable than composite materials and can create a tighter seal, especially under high pressure. The Viton coating on the embossed outer layers adds further resistance to heat and chemicals.

Does this gasket come with any installation hardware?

This product is for the head gasket only. It's recommended to refer to the manufacturer's installation instructions for any additional hardware or preparation steps needed for installation.

What is the purpose of the Viton coating on the gasket?

The Viton coating on the embossed outer layers helps to improve the gasket's sealing performance. It also provides increased resistance to high temperatures and various chemicals found in the engine environment.

About this part

Product Details

This Cometic head gasket is made from copper and measures 0.043 inches thick with a 4.320-inch bore, specifically designed for the Chrysler 426 Hemi engine. Copper is a great material for head gaskets because it's malleable and can conform to the surfaces of the block and head, creating a very tight seal, especially under the high pressures these engines can generate. The embossed outer layers are coated with Viton, a synthetic rubber that adds extra sealing capability and resistance to heat and chemicals.

This gasket is a solid option for rebuilding or refreshing the top end of your Gen-2 Hemi V8. It fits a range of classic Mopar vehicles, including models like the Dodge Charger, Plymouth Barracuda, and Chrysler 300 from the mid-60s to early-70s. Using a copper gasket like this can help ensure a strong seal for your engine's combustion chambers, contributing to consistent performance.
