Twin cams allow higher RPM by design, as setting the cams apart gives better angles for intake and exhaust ports.
Also, with a set of vernier gears DOHC's allow better tuning of both exhaust and inlet valve timing.

single cam =more low down torque
twin cam = more high rpm torque

You don't think that has something to do with the way the engines are tuned due to their respective rev ranges?

multi valve motors are designed to rev high
single valve motors are boring

Not that it counts for anything when you're hauling a car weighing in excess of 1500kgs!

Easy solution - Stick it in a car that weighs 900kg's, then add a pair of turbos just to be sure...
