I got it done at this place - http://www.revolution707.com/

It is 70 miles from me and it was a big pain in the ass to leave the car there and pick it up the next day, but I am glad I did it. The difference is amazing, definitely recommend it. The price I got quoted was 690, but I was able to get it a little lower. Some people here have paid less for this service, but I have absolutely no regrets.
Mike is supposed to send me some pictures of the valves from his cell phone, so I'll post them as soon as I get them.
