Or dumb person answering the phone at the dealership. <img src="/forums/images/graemlins/drunk.gif" alt="" /> You need to call back and talk to someone who knows what the heck they're talking about. Maybe ask to speak to a tech and not just a service writer.

I get flyers in the mail advertising $250 valve adjustments, but I don't know the details. Its a fairly labor-intensive project so I wouldn't be surprised if the total ended up being $4-500. But that's a TON cheaper than having the head(s) rebuilt because you burnt a valve or something.
