About this part

Product Details

If you're working on a Chrysler Gen-2 Hemi engine, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the job. It's designed with a 4.250-inch bore and a compressed thickness of 0.060 inches, making it suitable for a range of classic Dodge and Plymouth vehicles from the late 60s and early 70s, like the Dodge Charger or Plymouth Barracuda. These gaskets are essential for ensuring a tight seal between your cylinder head and engine block, preventing leaks and maintaining proper compression.

What makes these MLS gaskets stand out is their construction. They're made from multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482°F (250°C) and works well with different engine block and head materials, including aluminum and cast iron. This advanced design means you don't need to use any extra sealants; the gasket itself provides maximum sealing performance for high-output engines.
