Don't ever guess on ring orientation. Find the data. The chamfers create what is called ring twist in the rings action in moving up and down the bores; they angle in their grooves a bit more going one direction than the other. While the chamfers may be in the same or opposing direction in some engines, never assume that is the standard configuration for a particular engine; they can be all different, depending on what the engine engineers wanted to accomplish. The 'Top's and dots face up.
2M694 is a Hastings part number. 40787 is a Perfect Circle/Mahle number. So I suspect that this is an overseas set and they put on both numbers for the American market. (Google 'Hastings 2M694' or 'Mahle 40787'.)
The 'M' in the Hastings PN is for Moly faced top ring, and the Mahle PN is for premium rings (usually indicating a Moly faced top ring) What is bothering me is that I have never gotten a Moly faced top ring set where the Moly facing was not obvious on the top ring; it is always a silvery-grey color. I see that on neither ring here. But I don't know everything so I'd go back to the shop and ask about this; I don't think you actually have Moly faced top rings.
Do you have a ring installer? It will help you to keep the top 2 rings straighter in installation.
Those are both torsional compression rings, and install with the chamfers up. I'd check with the machine shop and make sure you have the correct 2nd ring set, ask if you need a reverse torsional ring in the second groove.
Note that the chamfers are quite different. I would assume for this engine to have a chamfered ring in the 2nd groove. (Ooops there I go assuming! Not good!)
