Tomei's Words: High Flow Design -1mm oversized valves were designed for increased flow efficiency on both the intake and exhaust side. The stem has a thinner design for maximizing the air flow rate within the port with the reduced air flow resistance. Precision Design -To maximize the potential of the valves purpose each factor was addressed during the design process from the surface of the valve head and the valve seat, the stem and cotter are all optimized with precision for optimum operating and sealing capabilities when needed most during extreme conditions.
