Just wanna let you know that everything worked out ok, I brought the head down and they put the vacuum on it and saw that they weren't all pulling 15 on the vacuum. They re lapped the valves and they seemed to be a lot better visually, they all pulled 15. Put the head on the car and everything runs good. I didn't have to sign any papers, they were pretty cool, they got it finished the same day. Thanks again for the answers.
