4bbl carb question

So I mocked up the carb on the engine today and a potential problem occurred to me. The way the carb sits, the primaries are in front and the secondaries are in back(in relation to the engines cylinders). So I'm wondering if under full boost, the front 2 or 3 cylinders will not get their fair share of gas. I'm just figuring in a NA engine the cylinders pull the mixture in more evenly from all 4 barrels. But under boost pressure I feel like it wouldn't disperse as evenly..anyone running a 4bbl carb(and preferably a turbo) ever think about, or investigate this?? I know the plugs will tell the tail, but I'm trying to figure out all these little kinks before the first start-up.
