Focus RS engine differences to a normal 2.0

Does anybody know what exact changes where made, obviously cams, rods and pistons where changed but what about head work, valves and valve springs, oil pump, water pump etc?

Thanks.

Tim.

Sodium-filled exhaust valves... Uprated valve springs.. Valve sizes are same as N/A, I doubt any porting was done (not necessarily for that power level)..
