Check to see that both of the main jets on the SU's are pushed up completely with the choke off.
Put a timing light on that engine and make sure your timing is not jumping around too.

If they were older carbs, I would have said to balance them using an air flow meter and then check the float level settings but not normally on rebuilt carbs.
With new or remanufactured/refurbished ones, I would still suggest balancing and it may even be worth checking the floats and float valves as they can sometimes stick or be set incorrectly. You might even have a bit of dirt or metal in the bottom of the float chamber left over from the rebuild that could be blocking things.
You might also want to contact the company that rebuilt them and ask if they set them up before they leave the workshop.
