Some people have no interest in porting a head, I don't want to do it anymore either when I can get a cnc head for a few hundred bucks more. The mancini rocker package is $520, hardly exotic, and not much more than any other roller rocker arm. You do not need a "radical cam" to take advantage of the trickflow heads anymore than ported speedmasters, they flow quite well at low lifts and are not "race heads". Some people want to spend more and get better quality parts and some are on a tighter budget and shop around, its up to the op as to how he wants to spend his money and he asked for opinions which we all are giving. It's great you are offering alternatives but at the same time just need to deal in facts and not what's good for you lol.
