About this part

Product Details

Cometic Gasket is known for making well-built sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's designed for Chrysler Gen-2 Hemi engines and features a 4.375-inch bore with a compressed thickness of .030 inches. This gasket is built to handle the demands of high-output engines, ensuring a solid seal between your cylinder heads and engine block.

This MLS gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and works well in harsh sealing environments. The center layer is uncoated stainless steel, allowing for precise thickness adjustments. These gaskets are suitable for use with both aluminum-to-aluminum and aluminum-to-cast iron block configurations, as they can manage the shearing forces that can occur between different metals.

This gasket fits a range of classic Mopar vehicles, including models like the Dodge Charger, Plymouth Barracuda, and Dodge Challenger from the late 60s and early 70s. Because it's an MLS design, it doesn't require any additional sealants, making installation more straightforward.
