Default 427 Weber Setup Recommendations

Putting a 427 SO together with 48IDA's and would like some recommendations on how to set them up since they came off of a running 289. I have zero experience with these so I want to defer to the experts. Engine is a 427 side oiler with 4.25 bore x 3.784 stroke, CR 9.5:1, 2.19 & 1.71 Int/Exh valves. Camshaft is an Inglese stage 2 HR with 234/236 duration, .586/.580 lift and 115 degree lobe separation. Manual trans @ 3,000 lb. Am using 10 degree cant on the carbs. Looking for the following:

Main jet size
Air corrector size
Idle jet size
Idle jet holder size
Pump jet size
Emulsion tube size
Venturi size
Needle valve size
Anything else pertinent

Does anybody have any running combinations I could use for this setup? Not looking to wring every last HP out of it, just want it to behave. Thanks in advance!
