Its really a matter of preference which one to use. If you go by the Weber manuals, you want the carb bowl forward and the smaller barrel opening closer to the motor. The dgev works that way with the throttle linkage at the back of the carb; the dfav has the linkage at the front. If you have an auto, you need the linkage at the back. other than the linkage position, the carbs are identical and all parts interchange. The bowl facing forward is to prevent surging when stopping while going down steep inclines. I have run both carbs on my 80 d50, and am currently running a dgev spun 180 degrees so the linkage is in the front due to the linkage adaptor I am using; not a lot of difference either way. Just use the one that works best and matches the way your linkage works best for you. I can send you a pic of how mine is mounted, although it is of the older 5 bolt adaptor setup; LMK.
