My rough hunch is the jetting will end up 67 to 70 pri (with functional power valves) and 75 to 78 sec. (or two #21 sec metering plates)
The power valve channel restriction will need work. The idle feed restrictions and idle air bleeds will need work.
And the high speed air bleeds will need fine tuning once best jetting is found.
The power valves need to be boost referenced so they operate correctly on the blower motor.
So they see the vacuum/boost signal below the supercharger and react accordingly.

The prority is to not test with a jet that is too lean. Ignore the smell of the exhaust at idle, for now.
(once the ignition fault is corrected)

If you are going to dyno test with the primary power valves plugged, start rich on the pri jet . #72+++++

Like I said before you should at minimum tear these carbs down and get them ready for the blower and dyno testing.

Boost reference the power valves
remove the chokes and the choke horns. ( do not remove the bowl vent tubes)
modify the secondary metering plates to accept standard screw in holley main jets.
blueprint the vac sec housings. (leaks)(spring)
