If it was assembled correctly with asseble lube, you will not have any prblems from it being stored on a stand for a couple of years. If I remember right, you have to prime the 200 oil pump. Before you get it in the vehicle, I would do this.
Everyone has their own beliefs on how to break in an engine. Mine is to run it a little, (not more than 50 miles), change the oil and filter, run it to 500 miles, change the oil and filter again. From there on you are golden. I have never had a problem using standard Quaker State 10-30 for this, and I run engines for a long time. BUt that's just my view...
