GUIDES
  • Titanium valves
  • Built from Xceldyne’s specified blend of Manganese-bronze
  • Features an advanced “High-flow” design
  • Heat dissipation (thermal conductivity) and valve stem lubrication are substantially increased,
  • to increase flow by more than 15% over
    which leads to extended valve stem life
  • Highest tolerances for correct valve stem support and fitment in cylinder head
  • Some models available with positive-stop “step” built in for easy installation and more
  • and horsepower
    importantly, the correct height
  • PVD-coated for outstanding wear-resistance
  • 2-piece, unless noted
  • in seat, tip and guide area
