Valves
When Scorpion Performance was looking to produce valves, they looked towards F1 technology when choosing their metals, which they claim allows their valves to be 10 grams lighter then other valves on the market. Their valves also come back cut, double swirl polished, and have heat treated tips.
Lifters
Another piece is their hydraulic roller lifters, which have been engineered with a 50 millionths tolerance between the piston and internal inner diameter of the body; each piston is matched specifically to a corresponding body. A chromoly roller axle prevents wear on the cam side while every lifter is leak down tested before boxed. They are available in both standard and high tie bar setups and Scorpion claims that these lifters will last to 8500 RPM, which is staggering for a hydraulic lifter.
Valve Springs
Scorpion offers their beehive valve springs in single to triple spring options, depending on application. The springs are made from high grade Kobe steel and are surface polished before entering the Nitride process that helps harden the metal.
