I have NEVER found a difference in performance, etc., between those 2 coils. I have always used the Magnetti- Morelli coil, on carb conversions back in the day.

Time to go a bit deeper- check inner cam bearings, oil pump, etc.

pushrods and lifters look good, jam nuts were still tight af, lifters dont have any wear I can see.

    And ...... 

well it's a start, guess I'll pull the covers off and have a look. s&s lifters in there also, so I might as well look at them while I'm in there.

 I agree, but apparently Harley doesn't think so that is what the Dealer got credit for. Back in 16, bike was new with 100 miles on it.   

I've had one on my TC EG forever.  It's a well built head pipe. 

The shop I used to work for followed then current ESP guidelines- if the bike was still under factory warranty (0-2 years old), use the flat rate manual; if out of factory warranty (2-5 years old), but still covered by ESP, flat rate X 1.25. If greater than 5 years old, flat rate X 1.5. This helps account for rusted/frozen hardware, + the older a bike is, the more likely it's been hacked up at some point. 
The closest job I would believe applies is 4321, Replace side door gasket, 2.8 hours, x 1.5 ESP multiplier, for a total of 4.2 hours.
16 is just criminal...

It's rare, but it happens- I have also had one or two of those jam nuts split over the years, inducing a lot of racket.

Is it really any other difference than the molded casing between 31655-99 (carb) and 31743-01 (EFI)?

Found the difference 😀
