Except for the added cost of the rocker set up for the Trick Flow heads, in which if you already have a roller rocker set up that works on the Pro Maxx/Edelbrock head, the Trick Flow, it is a win win.
What's the diff on the TF rockers? I thought they took a standard dimension rocker with no special offset, they just need to be able to clear a 1.550" dia spring? The PRW rockers that were in the pics on IMM's facechat site supposedly work. I dont' think many would try to run stock stamped rockers on $2000 heads
