Milodon Valves - Megaflow Competition
At a normal intake valve temperature of 1200 F, Megaflow Valves have a tensile strength of 85,000 PSI (equals 165,000 PSI at room temperature). At a normal exhaust valve temperature of 1400 F, Megaflow Valves have a tensile strength of 63,000 PSI (equals 165,000 PSI at room temperature). Deep hard chroming on stems for superior wear resistance. Smooth transition from stem to valve head aiding both flow and strength. Close tolerance stem grinding for no variation from valve to valve.
