This is what I have drawn on my garage door from those 1406 has together. I'm sure the 71-47 rods were the ones that were making the 13.7 to 14.2 at idle of course with the correct air blade adjustment. And I'm going to go out on a limb and say it was the number four Springs that I had in there..
I think the number three Springs and the 73-47 rods were something I was going to experiment with.. but I could be wrong. Let me check and see if I got something from my other notes as well..
