About this part

Product Details

When you're rebuilding the top end of your Chrysler Gen-2 Hemi, getting the head gasket right is crucial for a solid seal. This Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of these powerful engines, ensuring a reliable seal between your cylinder head and block.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound and resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This design means you don't need to use any extra sealants, and it works well whether you're pairing aluminum heads with aluminum blocks or aluminum heads with cast iron blocks, as it can handle the shearing forces between different metals. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.070 inch compressed thickness on this particular gasket.

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. It's a well-built option for anyone looking to ensure a proper seal during their engine rebuild.
