Designed for high power setups. Optimizes engine performance. Higher lift than other profiles of the duration. Reduced stress wear on the valve train. The VALC profile allows the valves to open faster and for longer. This translates to faster lift and increased area under the 'lift curve' (see fig. ) which in turn generates more power. (Greater area
