The chain can slip off the lower sprocket real easy, especially if the crankshaft was rotated.

I think (just MHO) that you align the crank at o|t and the cam with the two #1 lobes pointing equally "down", i.e., both equally offset from the "down" defined by the centerline of the engine, not by gravity. I'll have to learn for sure pretty soon here... my turn comes in a few weeks after the head comes back from the shop. Glad you're going through this first so I can learn...
