Depends on the manifold.......is it open under both carbs..........or does the front carb feed the front 4 cylinders and the back carb the other four?
If its wide open under the carbs{both carbs feeding front and back}it may be specified on the manufactures web site if the manifold was made with one or the other in mind for a primary.
If its seperate under the carbs ,no progressive linkage will work,both need to be primary and tuned for that use.

Might be a good idea to list exactly which manifold you have and the carb numbers and type.May get more meaningful help with more info.
Heres a search on google for tunning dual quads.
