Good point, my plan was to read the plugs and go off the best cylinder(s) as a reference.

Excellent! many things can guide you. I didn't speak to you noticing an 'issue' during part throttle and idle because distribution can be biased due to throttle blades IAB/carb tuning in general too. One thing i'll mention in addition is the INDY plenum IS SMALL. adding a spacer will help distribution as well.
