A lot of people just put in bigger valves because they flow more air. Ever heard of someone "unshrouding" a valve? This means you move the wall away from the valve to allow the side nearest the wall to flow properly. If you go too big on valve sizes, you actuall put a lot of the valve along and very close to a wall and thereby actually reduce the airflow of the head simply because 30% or so of the valve is not being used porperly or at all.
