The 48's are a dime a dozen!
The RA IV were a couple thousand dollars! The SD 455's were basically unobtainable! The reason is as said, when the aluminum heads came out, no sense in trying to go fast with cast iron round ports. They went to high dollar restored cars. This isn't to say there were none, because there were racers using the round ports. (like Beswick and others?) Class racers used them but not power adder.

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.
