Progressive linkage or all in.
My 360 breathes through all 8 barrels all the time and it rips. 6 should be fine if your comp ratio is decent.
Id be a little concerned at fuel/air mixing due to the low plentum volume of the adapter. So maybe tip in the center to get air moving then dump in the last 4 after?
Do you have a wide band in the car? Im not a fan of tuning multi carb set ups the old fashioned way.
