i'm in the process of rebuilding a 235. i think i'm going to use a duel carb intake. i've been told that they help distibute fuel and air into the cylinders more evenly. and they keep the 1 and 6 from running lean.

is a header (fenton) required to complete the equation or will it breath just fine without one?

also is there a alternate way to get even fule ditribuiton?
