What is the benefit of the HP shim technology?

The HP shim technology increases the clamping force around the combustion chamber. This is particularly helpful for open deck blocks, as it improves the sealability of the head gasket.

What does the Viton coating do?

The gasket is coated on both sides with Viton, a material known for its excellent resistance to heat and oil. This coating enhances the gasket's ability to maintain a strong seal under demanding engine conditions.

What vehicles does this head gasket fit?

This head gasket fits a variety of vehicles including the Dodge Charger (1966-1971), Plymouth Barracuda (1968-1971), and Ford Mustang (2015-2018), among others. Always verify fitment for your specific year, make, and model.

About this part

Product Details

Cometic Gasket is known for making well-built sealing solutions for performance applications. This Multi-Layer Steel (MLS) head gasket is specifically designed for Chrysler 7.0L Gen-3 Hemi engines, including those in RHS Drag Pak setups. It features a 4.200-inch bore and a .072-inch thickness, making it suitable for a range of performance builds.

The key to this gasket's performance is its HP shim technology. This design increases the clamping force around the combustion chamber, which is especially important for open deck blocks like those found in many Hemi applications. This improved sealability helps prevent leaks and ensures consistent performance under demanding conditions. The gasket is also coated on both sides with Viton, a material known for its resistance to heat and oil, further enhancing its sealing capabilities.

This head gasket fits a variety of classic and modern Mopar vehicles, including models like the Dodge Charger, Plymouth Barracuda, and Dodge Challenger from the late 60s and early 70s. If you're rebuilding a Gen-3 Hemi for serious performance, this Cometic gasket offers a solid option for maintaining a strong seal.
