F-body headers are F-body headers, regardless of induction system. Only difference is if they are smog headers or not.

That's not totally true, but pretty close. If you plan on hooking up to your stock exhaust system, there are different header/Y-pipe combinations to fit the different diameter cats, and also for the dual cat cars. If you are just talking about full length headers and don't care about smog hookups or going to cats, etc, then the original induction system makes no difference.

2nd gen headers in a 3rd gen F-body might see fitment issues. Sure they'll bolt to the heads and the ports will match, but the engine bays were different. I'm only saying this because I've never seen a header set sold as"69-92" model years. Also T/A's comment about Y-pipe configurations would definately hold true between 2nd and 3rd gen cars. I would just wait untill someone who knows for sure can comment or, if you already have them, try and tell us what happens.

When I said that F-body headers will fit any F-body, I was refereing only to 3rd gens. 2nd gen will not fit properly in a thirdgen. I was also refering to long tubes, since shorty headers are a waste of time and money.
