Cometic Chrysler Gen-2 Hemi .040in MLS Cyl Head Gasket-4.500in Bore

Built with a 4.500 inch bore and a .040 inch thickness, this Cometic Multi-Layer Steel (MLS) head gasket is specifically made for Chrysler Gen-2 Hemi engines, particularly those using Keith Black aluminum blocks with siamese bores. The advanced HP shim technology built into this gasket is designed to increase the clamping force around the combustion chamber. This is especially helpful for open deck blocks, as it improves the sealability of the head gasket in that critical area.

The outer layers of this gasket are embossed and coated with Viton, a material known for its resistance to heat and oil. This construction helps ensure a solid seal between the cylinder head and the engine block, which is crucial for maintaining compression and preventing coolant and oil leaks. This gasket fits a range of classic Mopar vehicles, including models like the Dodge Charger, Plymouth Barracuda, and Dodge Challenger from the late 60s and early 70s.
