Cutting Valve Seat

My friends '05 recently chewed up an intake valve. The valve sealing surface is cupped and the angles on the valve seat are somewhat mashed. He is replacing all valves with Kibblewhite and the rest of the valve seats are in good condition. He doesn't want to send the head off and there aren't any good engine building shops nearby. I have been researching the procedure for cutting valve seats and I believe it is something I could definitely do. However, I have found very little info on hand powered seat cutters and grinders. Does anyone know where I can find the required tools to do this job?

      As close to new as I'd imagine you'd get! I bought the bike brand new, I'm older and have taken extremely good care of this bike. Very little use and is COMPLETELY stock - everything is original. 
      Comes with the title, original book and map couplers for the fuel injection.
      $4700 - cash

      Time for a top end on my bike, just wondering if there are any alternative Valve springs i can use. I have PC cams and $400 for just the springs and retainers is alil costly at the moment.
      This has been fun in other sections of TT, so I'll start the thread here and see if we can keep it going.
      Let us know what kind of mods, fixes, changes, etc.., you performed today, or just general fun you had with, your KX250F.
      I'll start with.. I installed a correct for my weight Race Tech shock spring, along with a Pivot Works shock spring thrust bearing. Also cleaned out all the nasty yellow plastic/wax crap that passes for grease in the lower shock bearing, and re-lubed it with Bel Ray waterproof.
