That plus I believe that this is meant to be a relatively low RPM truck engine. The over head cams seem to help more at higher RPMs. I can't find it now but I saw a video a few weeks ago showing almost a ramp in the head design to add a lot swirl to the incoming air to get better fuel mixture for cleaner and more efficient burning. This could not be done with a four valve engine, hence the two valve design.
