Hedman USED to list 65 fit headers even in W2 flange but I dont see them anymore. If the DD8's fit the Early A's they really should advertise it so (no doubt they fit but its just strange they dont list it that way). Here are a few pics of some old Cyclones (with exhaust flanges) and maybe some old Hedmans with no flanges. both for early A's IIRC. (Thats why I would have them)
