The ram air style manifolds flow as well or a wee bit better than the "shorty" style headers that are available.Two part #s of shorty style headers are available from hedman the numbers areas follows, # 28164 is listed as fitting 70-81 firebirds and #28170 is listed as fitting 64-72 lemans/gto, as far as which will fit the g-body better I would probably bet my money on the #28170 myself though I have no way to prove for sure(just a guess). Both headers retail in the 225.00-250.00 range which makes the repo ram air manifolds the best sure fit option in my book as they are available in the 300.00 dollar area.And possibly someone with hands on experience can tell you if there is a decent low cost full length header that will fit that is for another application.
