I did my own valve inspection a few years back and it was one of my favorite experiences with this car. Taking apart that S54 and seeing all of it's interior sexiness was completely worth the risk*
From time to time you'll see shim kits being passed around on M3Forum and you basically pay a standard $200 fee or whatever it is, use it, replace the shims you took out of it, then sell it on the forum again for the same price you paid. At the end of it you'll only be out of pocket for the exact shims your car required. This is far, far less expensive than a dealer or shop will charge. Most of the shim kits I've seen also have the feeler gauge passed along with it.
*there's not much risk at all as long as you take your time and are very thorough. Took me an entire afternoon/evening to open the engine up, change the shims, and close it all up again. I also replaced some things with the Vanos as well while I was in there.
