FINALLY got the head back from the shop. They "found" my cam caps but I don't think they are mine. They didn't shave the head like I told them too either. I also didn't get my nuts and stud returned either for the caps. I'm going to take it to a machine shop that has done good work for me before and have them check the alignment of the caps and deck the head.
How much should I have taken off this thing so I'm just at the limit of compression on 91 octane? Keep in mind I have a 276* cam so dynamic compression will be much lower than stock.
