Here is the metering block from the front carb. Factory set with no power valve and 76 jets.

IIRC the 1850 metering blocks (the 600 vacuum secondary carb) will work. I would pin the emulsion and idle feed restriction and see where they are at. I’m certain the idle feeds will be smaller and that’s probably not a bad thing.
