Product Details
Cometic Gasket is known for making well-built sealing components, and these Multi-Layer Steel (MLS) header gaskets are a prime example. If you're working on a Chrysler or Dodge V8 engine from the LA series, like a 318, 340, or 360, these gaskets are designed to handle the demands of performance exhaust setups. They fit a wide range of vehicles, including classic muscle cars like the Dodge Charger and Coronet, as well as trucks like the Dodge D100 series.
These MLS gaskets are built with multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping to prevent leaks even under high stress. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and different surface finishes. This construction means you don't need to use any extra sealants, making installation more straightforward. The center layer is uncoated stainless steel and can be varied to achieve the specific thickness needed, in this case, .030 inches, with port dimensions of 1.310 inches by 1.640 inches.
