Cometic Chrysler SR II/ZB I Viper .027in MLS Cylinder Head Gasket - 4.165in Bore

This is a Cometic Multi-Layer Steel (MLS) head gasket specifically for the Chrysler SR II/ZB I Viper engine, designed for a 4.165 inch bore. It's built to handle the demands of high-output engines, offering a solid seal without needing extra sealants. This gasket is a good choice whether you're working with aluminum heads and blocks or a mix of aluminum heads and cast iron blocks, as its construction can manage the stresses between different metals.

The gasket is constructed from multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is designed to perform well in tough sealing conditions, under various loads, and on different surface finishes. The center layer is uncoated stainless steel and can be varied to achieve different gasket thicknesses; this particular gasket has a compressed operating thickness of 0.036 inches, starting from a nominal thickness of 0.027 inches.
