I've done it twice. I used engine brushes, Chemtool B12, carb cleaner and a shop vac. Process is simple once the intake manifold is removed, soak the closed valves in B12 wait 20-45 minutes then go to town with the engine brushes once finished suck up dirty residue with shop vac. Once that's finished spray the closed valves with carb cleaner then again go to town with the drill then suck up the residue when you are finished. This process will need to be repeated a few times (till the valves are clean). Once those valves are clean rotate the crank and work on the other valves. In my experience you should have 4-6 valves closed at once. Be sure to suck up all the residue with the shop vac you don't want any lingering particles when you are done.
Here are is my before and after at 40K miles. Didn't notice much of a power difference just better idle and throttle response but my valves weren't that bad. I'm sure if they were worse it would have impacted performance a lot more.

I use the engine brushes with a drill.
