Cometic Chrysler 6.4L Apache Gen-3 Hemi .120in MLS Cylinder Head Gasket - 4.120in Bore - LHS

If you're rebuilding the top end of a high-output Chrysler 6.4L Apache Gen-3 Hemi engine, getting the cylinder head gasket right is crucial for sealing. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these powerful engines, ensuring a solid seal between your cylinder head and block.

Cometic constructs these gaskets with 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. This construction means the gasket can withstand the forces created when mating different block and head materials, like aluminum to cast iron, and it doesn't require any additional sealants to do its job. The center layer is stainless steel and can be varied to achieve different compressed thicknesses, with this particular gasket having a compressed operating thickness of 0.036 inches from its 0.120-inch nominal thickness.

This gasket fits a range of popular vehicles, including models like the Dodge Challenger, Charger, and Jeep Grand Cherokee, making it a solid option for many rebuild projects. Ensure you consult the manufacturer's instructions for proper installation procedures.
