Beyond which it sounds like you are putting the same parts back on the engine after they have been reconditioned, correct?
#2. Rather than dragging the engine back to the machine shop OR trying to force them to come to you why not just remove the front cover and fix the problem yourself. Its no big deal. We'll walk you thru the correction. We've done it many, many times for others. The worst it'll cost you is a front cover gasket set.
The other suggestion I would make would be for you to loosen ALL of your rocker arms such that NO valves open until you get the cam set up correctly. After you get the cam phased correctly with the crank then readjust your valves.
