I've recently come across a video of the factory production of the S54 engine found here https://www.youtube.com/watch?v=ZjFVV5HXU0Q&frags=pl,wn
It's interesting to see one of the technicians blowing a little bit of magic onto a part at 1:55.
Also, from 3:15 you can see the rotational order of the cylinders. As you can see, the cylinders rotate in pairs, like two in-line 3 cylinder engines. I had previously assumed that the 6 cylinders would be phased at 60 degrees in their firing order, so this was a revelation to me.
