About this part

Product Details

If you're rebuilding the top end of your 6.1L Hemi engine in your 2005-2010 Chrysler 300, a reliable head gasket is crucial for sealing combustion pressure. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output 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 additional sealants. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.040 inches compressed thickness on this particular gasket, which is designed for aluminum blocks.

This gasket is a well-built option for both aluminum-to-aluminum and aluminum-to-cast iron block configurations, capable of withstanding the shearing forces that can occur between different metals.
