I read a quote by "Dyno" Don Nickleson about the A3 heads. I think it was around the time he had the BB with the Motorsport aluminum 429 CJ head engine.
It was kinda of a negative one in that he said he got more HP out of the iron "high port" race heads then the A3's are capable of.
I always thought they were more "trans-Am" heads.
See, and I'm critacised for being harsh.
