Our ZZP Viton coated MLS head gasket is the sealing solution for high boost LSx applications. We start with our normal multi layer steel head gaskets and add an extra sealing layer of Viton coating. Viton is a synthetic coating that's designed to withstand high temperatures and remain flexible when introduced to chemicals and high cylinder pressure. Though thinly coated the Viton coating can flex leaving the head gasket in-tact. If you're rebuilding your engine or replacing the stock head gasket and want to hold boost safely, this is the gasket for you. Also makes a great stock replacement. No copper spray needed.
