so is the cam thats needed more duration or more lift? i would guess you want a faster ramp to open them and less overlap but not more lift? faster ramp would mean better springs to control the lift/close speeds. from what i understand big lift is not needed on turbo motors, just the time the valve is open, the turbo is pushing the mix so you dont need the lift, but you want the valves open for as long as possable with the least amount of overlap.
