Cometic Chrysler 318/340/360 4.040 inch Bore .030 inch MLS Head Gasket (Non SVO)

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed operating thickness of 0.030 inches and is designed for a 4.040 inch bore, making it suitable for Chrysler 318, 340, and 360 cubic inch LA-series V8 engines. The gasket's construction utilizes multiple layers of stainless steel for increased strength and rebound capability, while the outer layers are coated with Viton, a heat-resistant synthetic rubber capable of withstanding temperatures up to 482 degrees Fahrenheit. This advanced design ensures a reliable seal for high-output engines, whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, and it doesn't require any additional sealants.

The multi-layer steel design inherently offers improved sealing performance compared to traditional composite gaskets. The embossed outer layers with Viton coating are specifically chosen to handle the demanding conditions found in modern engines, resisting corrosion and providing a durable seal across various surface finishes and load conditions. The center shim layer is uncoated stainless steel, allowing for precise thickness control. This gasket is a solid option for rebuilding or upgrading engines in a wide range of vehicles, including classic Mopars like the Dodge Charger and Chrysler Cordoba, as well as trucks like the Dodge D150.
