1g is most likely being put to rest soon. Besides it was a 7bolt too. I could also use a 6bolt head too, but I'd like to keep it 7bolt. Have a guy that knows how to weld cast so may just modify some manifolds to fit (chop off 6bolt flange weld on 7 bolt flange and port match). Not this one right away, seeing how rare it is, but some normal cyclones to begin with.
