I have to be honest and tell you I only have had the B/E body super comps. Tubes are close together but not equal. Excellent header for the small block. The fit great.
Super are supposed to be balanced same length tubes and larger size.
I have the Supers been on car since 2004 bought 4 or 5 years before but are A body part the Challenger I bought few years before were not the same part number
