I never found the starting orientation of the crankshaft an issue, but you will have to bring the three rods out through their respective holes as you bring the halves together. You can make three cardboard supports that will hold them upright. Don't forget the camshaft chain, it needs to be brought out as well. Your best bet here is a second person. My wife knows how to do this like an expert, but she has become very expensive....
Good luck.
