Yes, the one I have seen online had the same modifications. I read an article from back in the day where the were building all of the 455 engine identical to each other. They sourced used engines and bored them to 462 for a basically new engine. The article stated that they also used a specific head for 9.2 compression ratio and enlarged the valves to 1.77. My car has 6X heads though I don’t know if they are 6X-4 or 6X-8.

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.
