Yes, Circle Track has Jim McFarland and Dennis Wells work on a regular bases, back in 2002 Circle Track did a long Air flow Article that led me to dye testing.
I also have used dimpling just in case of fuel crash on the chamber wall as Dennis calls it. I don’t know if it helped or hurt because I cannot afford to do back-to-back Dyno test.
The dye testing is questionable as well, unless you can do it with intake and carb, and some how duplicate engine conditions IE; heat, speed and pulse from ram effect.
Plus trying to duplicate the flow disturbance from the overlap of the opposite runner is near impossible. However, I guess if it’s done enough in conjunction with Dyno time and you see improvements, it’s worth the extra effort to learn as much as possible.
