72' Bonneville Headers
The car I'm doing some work on is a 72' Bonneville with the 455 engine. I'm installing a set of 6X heads on it that has all the exhaust manifold bolt holes and the customer wants to put headers on it. Does anyone KNOW what headers will fit this car? I would lean toward early Firebird headers but I'm not sure.

I’m no expert, but the 3 tube headers for a 2nd gen F body, I would think to have a great chance of fitting.

2nd gen F-body car headers will fit fine, use the 4 tubes for better performance.
The HO manifolds will also fit perfectly fine:

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.
