If both engines are doing the same thing I cannot imagine it being something in the distributors. Chances of both of them failing at the same time in the same way are pretty darn slim.
I would be going through the entire electrical system and checking all connections. Especially grounds. Take every thing off, wire brush the terminals and put it back together.

Delco Voyager EST igniton
See last sentence of post 18.
Not sure if that applies to your setup or not but might explain no change in adv.

I believe your idle circuit is too rich. I set my idle 13.7 and as much timing as I can. My new EFI setups needed me to up idle timing to 32° so it wouldn't stall during shift. I ran 2 different timing curves with those cams; locked 35° and 28°-36° High Idle on my Crane HI-6M's. I only netted 8° not the 10° it advertised, my light could have been off too.
I’ll need to baseline the transition slots again and this time actually try setting everything in gear.

Gotcha. Sounds like a bad ign module as you suspected prev.
It will be interesting to see if the other eng has the same "no adv" issue.

Thinking a couple of issues… carbs out of whack. And something odd with this distributor.
