About this part

Product Details

If you're rebuilding the top end of your 2005-2010 Chrysler 300 with the 6.1L Gen-3 Hemi engine, 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 harsh sealing environments and various surface finishes, ensuring a tight seal without needing additional sealants. The center layer is stainless steel and can be varied to achieve different compressed thicknesses, like the 0.051 inch thickness of this particular gasket, which is ideal for an aluminum sleeved block and a 4.185 inch bore.

This gasket is designed to work well with aluminum heads and blocks, and can handle the shearing forces that can occur between different metal types. It's a well-built component for a serious engine build.
