Howdy. Welcome. #62's are good large valve heads. Your car should be a 350 horsepower 400. Thirty five years and at least I believe you said 27 owners anything is possible. There really wasn't a "smog" head in that time frame. Unless manufacturing large quanities of smog meets the requirement.

LOL@Davey
 #62 heads were 1969 large valve heads usually found on '69 GTO's or Firebirds and Automatic '69 Judge's.

I don't remember any smog heads but I do remember asking why my 70 GTO didn't have an air pump which was very on Chevys. I was told that it wasn't needed do to the head design. ? Sounded okay to me. My SS396 buddies all had them though.

I think the Pontiacs that were sold in CA had Smog Pumps on them?At least I remember seeing a '66 GTO that was set up that way?

I would say the resonators are somewhat rare. I purchased a pair at the 1985 POCI show in Denver. They now reside on my 69 automatic GTO. Most people don't have the correct tailpipes/resonators on their car. It is a detail most people overlook. Good for you for obtaining them. I sure you could sell them should you so desire.

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.
