On weber carb set ups, I sync the front carbs to the rear carbs on each side using spring loaded balance screws, THEN adjust the linkage hex rod between them to balance left bank to right.
If there is a vacuum difference between venturies of a carb, it usually indicates a twisted throttle brass throttle shaft. When screwing on linkage arms, they are easily twisted, the good news is you can tweak them back. All v8 webber set ups should have the linkage pull between the carbs, not pull on the front or rear ends.
