Did you join, and were you in the correct forum? I think that either here: http://forums.performanceyears.com/f...play.php?f=428 or here: http://forums.performanceyears.com/f...play.php?f=450 should do it.

GTO headers won't fit because of the different front cross member location, and there are no shorty headers for the Pontiac engine. 67-69 Firebird headers will fit - sometimes with hardly any modification, and sometimes with a little hammer help. Left side is mainly interference with steering box and pitman arm, and right side with possible idler arm interference. I believe that you need to substitute out the 90 degree oil filter adapter for the adapter found on Firebird's and GTO's that angle the adapter bottom more towards the pan for more clearance.

Even with the Doug Headers made for our '65 2+2, we had to fabricate a new transmission cross member because the kick-ups in the X-member were too close to the trans to run the tailpipes back from the collectors. I always wondered if using the Firebird headers instead might have moved the bottom of the headers inward enough to use the stock B-body X-member.

Also try the search function on the PY Forum for old posts on header compatibility with the big cars.

thanx ima look into that but yes they do have shorty headers for pontiacs they sell em at summit racing for 280 a pop and the main issue im worried about is the starte looks like its gonna be in the way, the frame looks pretty close and the car is pretty low to the ground other than that it looks like it will be easy to route the pipes and all but i though the shorty headers would make it a lot easier on me.

the shorty headers were for a 64 and up 389 engine i know they will fit but i wasnt sure on how the tubes were routed but i guess if there shorty headers it wouldnt make a difference
