Vacuum secondaries all the way unless you leave every stoplight by dumping the clutch at 7500 rpm. Get the vacuum pot covers that have the nipple sticking out so that you can link the two vacuum pots together with a length of vacuum hose a la factory ford dual quad setups. If you can feel the secondaries "open" what you really are feeling is when your motor finally has enough airflow to overcome the bog that it was operating in due to the secondaries already being open and the motor being overcarbed. You can play with the secondary vacum pot springs, but absolutely do not remove the check ball from the vacuum pot. The secondaries will just flop open instead of making the smooth transition. Also, put a tiny bit of progressive into the linkage, so that one carb starts to open the primary throttle blades a wee bit before the other carb. Dual quads really liketo have downleg boosters in them instead of the straight ones. Good luck
