Two Carter WO carbs for the 134 cubic inch Jeep 4 cylinder will only slightly over-carburete a 216- - - - -they can handle 268 cubic inches. That's far more capacity than a 216 can use, but at least it won't have as many flat spots, backfires, and twitchy throttle response quirks as one with a pair of carbs that can feed 432 cubic inches, or 470 cubes, right?
