I never had any intention of running them completely out of the box without a thorough cleaning and inspection by at least me if not better. At this point I'm considering a machinist straight edge and my own dial gauge...
Honestly, you could do this yourself. I wouldn't be afraid of it one bit. Mostly you'd be taking them apart and cleaning them well. I would check them over like you did your cast heads that you had apart and put back together.
