Duttweiler (sp?) the guy who built the 450HP focus using a 2.5L duratec said that we do not need larger valves because the ones on there now are large enough, plus you get 4 per cylinder. Now Kinetic racing also agrees with this, anyone have anything to go against it, and if you do please explain WHY?
