About this part

Product Details

Starting with a compressed operating thickness of 0.036 inches, this Cometic Multi-Layer Steel (MLS) head gasket is built for high-output Small Block V8 engines, specifically those using Dart or Brodix blocks. It's designed to provide maximum sealing performance without needing additional sealants, making it a solid choice for both aluminum and cast iron block combinations. The multiple layers of stainless steel give it increased strength and the ability to rebound, helping it resist corrosion and withstand the shearing forces that can occur between different block and head materials.

The outer layers of this gasket are embossed and coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is tough enough for demanding sealing environments and various surface finishes. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements, like the 0.056-inch thickness of this particular gasket. This design is well-suited for a wide range of vehicles, including models like the Chevrolet Corvette, GMC C1500, and Avanti II, offering reliable sealing for many performance applications.
