Just benchracing a few thoughts with some freinds: 
You have a motor with a ROOTS type supercharger making 375hp.on a dyno.
Cam is 108C/L and 68* overlap 284* duration.
Makes 6-lbs boost.
Swap cams to a 114 C/L 56* overlap 278/290 duration cam, same 6-lbs boost,,,,,,, How much power difference would you expect????????? 
Just joining you guys on the bench racing here  ...........my thoughts would be the less overlap the better with only 6lbs boost as cooling wont be an issue , too much overlap when using boost will have air/fuel wasted out of exhaust port , boosted engines will tolerate a later opening intake valve due to difference in manifold pressure over non boosted...........not sure a split pattern is the best way to go with the boost you're running , the later closing exhaust valve may hinder cylinder fill.
