Cometic Chrysler 6.1L Gen-3 Hemi .027in MLS Cylinder Head Gasket - 4.100in Bore

When you're rebuilding the top end of your 6.1L Gen-3 Hemi engine, a solid cylinder head gasket is crucial for a good seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, offering a reliable seal without needing extra sealants.

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. This construction is effective whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as it can manage the shearing forces between different metals. The center layer is stainless steel and can be varied to achieve different gasket thicknesses, like the .027 inch thickness on this particular gasket, which also features a 4.100 inch bore.
