About this part

Product Details

If you're rebuilding the top end of your Dodge Challenger, a reliable head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the pressures of performance engines.

Cometic's MLS design uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes, ensuring a solid seal without needing extra sealants. The center layer is stainless steel and can be varied in thickness; in this case, it's set to provide a compressed operating thickness of 0.036 inches, with an 89mm bore and a .060 inch overall thickness, making it suitable for specific engine builds.

This gasket is designed to work well with both aluminum and cast iron blocks, and it can handle the shearing forces that can occur between different metals. It's a well-built component for those looking to ensure a proper seal during engine work.
