Product images may differ from actual product appearance.


Scorpion Extreme Duty Racing Valves offer the most popular and best high-performance stainless steel racing valves available for Small Block Chevy, Big Block Chevy, Corvette LS1, and Ford. Proudly made in the USA.


Intake Valves
  • Non-magnetic stainless steel 21-4N, a superior alloy 10 grams lighter than the competition yet durable enough for rigorous endurance racing applications
  • One-piece forging for maximum durability
  • Heat-treated tip 54 HRC minimum
  • Hard chromium stem with superfinishing for a much better surface finish
  • Double swirl polish with finer finishing
  • Back-cut for important flow improvement
  • Lightweight design with undercut stems to reduce weight and improve flow figures
  • Very tight tolerances to allow smaller guide clearances reducing oil consumption through the guides

    Exhaust Valves
  • Non-magnetic stainless steel 23-8N, a superior alloy for higher temperatures and closer to Inconel than any other valve steel
  • Hard chromium stem with superfinishing for much lower surface roughness
  • Heat-treated tip 54 HRC minimum
  • Double swirl polish with finer finishing
  • Back-cut for important flow improvement
  • Lightweight design with undercut stems to reduce weight and improve flow figures
  • Tapered exhaust undercuts to increase strength at high temperatures
  • Very tight tolerances to allow smaller guide clearances reducing oil consumption through the guides
