Yes, closest to the nozzels are the HSB (high speed bleeds) and the outers are the LSB (Low speed bleeds or idle bleed as some like to call them)
Just verify they're 31/70
I went all the way back to your post #29, and spent a lot of time with the pause button..
It looks like the only fuel it's getting is with the pump shot. I don't see much of any pull (fuel pull) in the boosters. Video is not ideal. I would like to see the same only in 3rd gear against the converter (short raps like you did) to see booster activity.
This confirms my suspicion your low bleeds may be incorrect.
Skrews provided a nice chart in post #30 to show what the carb should be set up with.
To re-iterate, I suspect your carb may need different bleeds with the Density Altitude you're running in.
