My question got lost in all the superb discussion about cutting edge FI activity. Dan H made a convincing argument that intake imbalance is a composite of manifold, runners , heads and exhaust characteristics. the vertical sump is noted to probabably be the worst case.
Don R reported some very encouraging numbers (egt balance ) with mechanical FI. One post referenced a scenario where in a significant CHT imbalance was improved buy manipulating the rubber gaskets in the intake system.
My question is, Why not use restrictors in the tubes between the sump and head to "tune" the air flow rate and thus optimize egt spread. For a carb engine, it would be an option although not as convenient as nozzle change for AFP or pushing buttons for EFI.
