I think the Pure Street guys have proven that a set of properly prepared AFR 165's will make more power than a 40somethingcc iron head. Definately the the most popular are the AFR's and TFS TW's. I'm going to try a set of irons on the dyno to see what I can get out of them. But I am planning on running the TW's.
