About this part

Product Details

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for your Chrysler 6.1L Gen-3 Hemi engine. You get one MLS head gasket with a bore size of 4.185 inches, built for an aluminum sleeved block. This gasket has a compressed thickness of .086 inches, which is important for maintaining proper compression ratios after engine work.

Cometic builds these gaskets with multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that seals well against aluminum heads and blocks, even with different materials like aluminum heads on cast iron blocks. This construction means you don't need any extra sealants for installation, and the gasket can handle the stresses of high-output engines. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .086 inches on this specific gasket.

This gasket is a solid option for rebuilding the top end of your 6.1L Hemi. Make sure to check your engine's specific bore size and block type to ensure this gasket is the right fit for your build.
