About this part

Product Details

If you're rebuilding the top end of your Chrysler Gen-2 Hemi engine, getting the right head gasket is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring reliable performance for your build.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in tough sealing environments. The compressed thickness of this gasket is 0.036 inches, and it features a 4.280-inch bore, making it suitable for a range of Gen-2 Hemi applications. Because it's an MLS design, it doesn't require any additional sealants, simplifying the installation process.

This gasket fits a variety of classic Mopar vehicles, including models like the Dodge Charger, Plymouth Barracuda, and Dodge Challenger from the late 60s and early 70s. It's designed to work effectively with both aluminum and cast iron blocks, and with aluminum heads, resisting the shearing forces that can occur between different metals.
