I think you are supposed to clean the valves every 1000 miles.  I have 1200 on my '02 700 and have yet to notice any decrease in performance, I will probably wait until the endof the year.  As far as having more power I know the difference between my valved and non valved 700 is night and day.

Are you sure the machine was stock? I am one of those guys that will tell someone a machine is stock when in fact it isn't. Most guys are starting to catch on now. Maybe he just has his dialed in better then yours from the factory.
 As far as the valves go I would clean them. They can never be to clean. Your first tank full should of had extra oil in it and probably not synthetic. When you clean do not try and remove the nuts on the end of the valves.

About every 1000 miles. If you have any trouble cleaning them use some gasket remover and an old tooth brush. Carefull not to score the metal on the valve and coat it with some oil when you put it back in.  Any easy way to check is to remove the caps and move the valve in and out with your fingers.  Then you can see if you are sticking some were.  But seriously our buddy is pulling your leg.  Hes not stock and if he wasent he wouldnot tell you anyways.  Good luck
