I sent my N47 of to a local machine shop for a cam regrind (out sourced), valve seals and cut/seats, new lash, rockers, lash pads etc. Told the guy not to removed the cam retainer caps...well I guess the caps were removed. Every manual, forum I have read states DO NOT REMOVE CAPS. They are still working on the head at this point and it has yet to be installed. From what I understand there can be alignment issues with the bearings, thus big time failure. This work is being done on my donor head, and I have my perfectly working stock head still on the car. Any input would be greatly appreciated.

1978 280Z all stock.
