When properly installed, the tangs on the rod caps that hold the rod bearings in place should all be pointed to the outside of the block. Pistons may have a notch on the top. That notch goes to the front of the engine.
My advice would be to purchase a YBlock engine book before assembling your engine. I have an old dog eared copy by James Eickman that I have had for many years. The rings need to be properly staggered. There may be instructions in the box with the rings.
