It seems like adjusting the valves on these things is probably a pain in the ass.

I kinda doubt valve adjustment is the problem. If I remember the post correctly, the "dealer" told him that. Yes, it was running fine.
It may just be coincidence, but during the time my car was throwing those codes, my 1* cat was going bad. It finally got so bad, the car wouldn't make it out of my neighborhood. Compare readings on both 02 sensors, upstream and downstream temps, and if you can, upstream back pressure.
