Cometic Chrysler 426 Hemi 4.31in Bore .040in MLS-4 Head Gasket

This product is a Cometic Multi-Layer Steel (MLS) head gasket designed for Chrysler 426 Hemi engines. It features a 4.31-inch bore and a compressed thickness of 0.040 inches. This gasket is built to handle the demands of high-output engines and is suitable for applications using aluminum heads with either aluminum or cast iron blocks, as it can manage the shearing forces between different metals.

The gasket is constructed from multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can withstand temperatures up to 482°F (250°C) and performs well in harsh sealing environments. The center layer is uncoated stainless steel, allowing for precise thickness adjustments. These MLS gaskets do not require additional sealants for installation.

This head gasket fits a range of classic Mopar vehicles, including models like the Dodge Challenger, Dodge Charger, and Plymouth Barracuda from the late 1960s and early 1970s. It's a solid option for rebuilding or maintaining the top end of these iconic engines.
