408 6 pack carb jetting

Just got my new 408 stroker assembled and I am going to run the LA six pack set up so was wondering if anyone out there has a carb tune for this setup? Specifically,What jet size for ctre carb and what vacuum spring color for the out boards?
The stroker has MP flat tappet 508 lift cam, about 9.5/1 CR, MP electronic dist and orange box. Car has 4 speed with 391 gear.
Would like to get this close initially so I can break in the motor. Once that is done I can fiddel with carbs ! I have an AEM wide band set up and put bungs in my exhaust so that will help later with tuning.
