440 HP manifolds vs. headers

The Hi-po exhaust that exits behind the #7 stud on the driver side shouldd fit most chassis as they fit my '65 which in all aspects seems smaller dimensionally. Those original A manifolds have a serious pinch point and the C body ones that are similiar exit right into the steering shaft. The Hi-po's were the only ones that I would consider. Those pictured are repopped now by Accurate if you are hard up on a set, about 400 a side I think.
