Cometic Chrysler 6.1L Gen-3 Hemi .045in MLS Cylinder Head Gasket-4.185in Bore-Aluminum Sleeved Block

If you're rebuilding the top end of your 6.1L Gen-3 Hemi engine, especially one with an aluminum sleeved block, a solid head gasket is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures of high-output applications, ensuring a reliable seal between your cylinder head and the block.

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 without needing additional sealants. The center layer is stainless steel, and its thickness can be varied to meet specific requirements, with this particular gasket offering a compressed thickness of 0.045 inches and a bore size of 4.185 inches, suitable for aluminum heads to aluminum or cast iron blocks.
