I'm not aware of any site that has a "chart" of jets to use with xxx mods on xxx bikes. I would think that compiling a list like that would take some doing since the possible combinations of bike size/model/carb type/exhaust type/ and other mods could all effect what jets you needed.

As for the lean running now, there are lots of reasons it could happen. It could be something was done wrong at the shop. Have you taken it back to the shop that did the work to see what they had to say? The original owner may have had the mixture set too rich to compensate for the leaness, trash in the fuel dislodged and is partially blocking jets or fuel flow now. First thing I would do is check for trash in the carbs and while in there check the main/pilot jet sizes. Check the factory jet sizes and see if they have been changed. If it still runs bad try to find someone with a similar bike/setup and see what size jets they are running. Try a larger main or pilot jet depending on the exact symptoms.
