I’d say it’s a culture thing. I believe Jim Hand ran em, and when I first got my car, lots of guys recommended to get his book. Pontiacs seem to be unique in that there’s a big desire to run factory parts: Qjets, iron intake manifolds, ram air manifolds and until recently, iron heads. I’ve only been on the scene for 6 years, but I’d wager it was due to lack of aftermarket support back in the day.
I picked up a set for a possible 455 build. Cliff has said that a 9.5-10:1 CR 455 is a great match for a Crower 60919(very close to an 041 cam) and Rhoads. He went on to say it gave up very little compared to a hyd roller that he dynoed.
So I suppose with the proper cam selection and Rhoads you could have similar performance to a roller, for less coin.
