Multi carb

[1971 cheburban]

I'm really thinking about going with six deuces. Don't know why, but I've always wanted six deuces on an engine, but finding an intake that's reasonable ain't easy. But I finally found an offy for 3 and half. I wanted to know if anyone has ever had any big problems with offy intakes or with the six deuce setup, how hard are they on gas, I mean I don't really care( if I did I would restore my sunfire) but like 6 or 8 to the gallon, are they hard to set up, what carbs are recommended and all that good stuff
