What style of exhaust manifold will fit the 1st gen B-body?
I have a friend that just picked up a 69 Firebird. The engine has some 3 tube headers on it and he want to go back to stock manifolds. What type will fit this chassis? Will ones from a 68-72 Lemans-GTO work?

 On the passenger side the rear-dump GTO/Lemans manifold fits/interchanges.  The '67 -'69 F-body driver's side uses a center-dump exhaust manifold, the GTO/Lemans manifold won't fit.  The center-dump driver's manifolds are also used on some '60s big Pontiacs (B-body) and '69-'70 Grand Prix (G-body).

 Thank for the info. That's what I thought worked but just couldn't remember for sure.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
