SCE Titan Self Sealing: The World's First Self Sealing Copper Head Gasket! The New SCE TITAN self sealing copper head gasket needs no sealant; it provides unbeatable strength and user friendly installation. This patented product gives you the best of both worlds, the combustion sealing strength of an SCE copper head gasket and the confidence of built-in coolant and oil seals! The perfect racing and performance head gasket! Precision fluid seals are bonded to both sides of the gasket around coolant and oil passages to prevent seepage or leaking. Sectional view shows how the unique seals are offset rather than stacked, allowing the annealed copper to deform around the seals as the head is torqued creating a "trough" which limits lateral deformation of the seal and provides metal to metal contact at the o-ring combustion seal. The design of the SCE TITAN was developed over eight years of experimentation with various methods and materials to provide "mission critical" characteristics in an easy to use product. Currently in use on Sprint Cars, Midgets, Boats, Jr. Fuel and also for Nitrous, Turbocharged, or Blown engines on the street.Pit Stop USA offers SCE SB Chevy Titan Copper Head Gaskets 4.060" x .062" T11066 at low everyday prices.
