About this part

Product Details

If you're working on a Dart or Brodix Small Block V8 engine, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for rebuilding or performance work. It's designed with a compressed thickness of .080 inches and a bore size of 4.270 inches, with a 4.500-inch bore center, making it suitable for a wide range of vehicles from 1980 through 1986, including popular models like the Chevrolet C10 and GMC C1500. These gaskets are built to handle the demands of high-output engines.

Cometic constructs these MLS gaskets from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping them resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. This construction means the gasket can be used with both aluminum and cast iron blocks and heads without needing additional sealants, and it's built to withstand the shearing forces that can occur between different metal types.
