Intake Valves

Each kit includes stainless steel valves, High-Rev valve springs, steel retainers, and Viton valve seals
Stainless steel valves are made from a one-piece forging out of 21-4N stainless steel
Valves go through a black nitrided hardening treatment which decreases valve wear and improves performance
High-Rev springs are heat-treated and stress-relieved, which dramatically increases the springs life cycle
Valve seals are made with Viton rubber which allows for greater seal and less stiction
