High lift cams give more torque without any effect to the power band so they are worth having.
As Steve has said long duration camshafts push the power band up the RPM range a must for big BHP but no good for low rpm response.
If you are pushing enough air through the head the long duration cams will help lag, but will make it worse on lower BHP engines
