If they really are that opened up (which I doubt but have seen done before before) then they will run like crap. You'll be severely limited at the valve which will lead to a VERY lazy port and a lot of problems. I'd forget about running those heads. as far as carb size- just double the hp level you want to get the cfm you need.
