Just an update, that price was just to clean it. I found 2 places that would clean and do a valve job. One was $85 for labor only and one was $125 labor only. I went with the $125 since it was just a couple miles from my house and the other was about an hour away. I had them replace all the valves since they were very worn and were original to the truck. It looks great and they even repainted it for me.
