Shower faucet stiil drips, despite new washers, stems, etc:

We have a shower where both the faucets drip. We have replaced internal washers, and replaced stems. Replacing either one helps, but not perfectly (usually there's still a slow drip after fixing). The drip gets worse over a period of weeks until it's nearly a trickle, at which point we take the faucets apart and do it all over again. It's gotten a little bit boring.

We've bought new stems a couple of times. They are the closest we can find (Kohler 6N-2 for any experts out there), but they are not EXACTLY the same size as the original (sub millimeter differences in a couple of places). I believe this is in fact the same model as the original, and the differences are not supposed to be important--but maybe they are.
The new stems come with O rings. The O ring always has to be removed to get the new stem to fit into the housing. If it is left on, either we can't thread it at all, or it threads, but then the stem has too much friction to turn. This seems wrong. Still, removing the O ring works far better than leaving it on.
If you're not a plumbing expert, you might still have new ideas on where I can get help with this. Here's where we might go next:
1) Call a plumber. If it would actually fix the problem permanently, I'm happy to call in an professional. However, I'm not convinced a random plumber will do any better than put in a new stem, fiddle with it until it stops dripping for the day, and four weeks later we're back where we are now.
[Or, don't call a plumber, but call a general contractor or a ??? instead.]
2) Take examples of stems and washers to a specialty plumbing store and hope we can find someone who can tell us what the underlying problem is and how to fix it.
3) Something else.
Thanks for advices.
