I don't dispute that the bloomer heads are top notch for a std. port head and make more power but I don't consider them to be in the same category as the trickflow. They have larger intake port than most ootb intakes can be ported to, are roughly 1K more than trickflows and add the fact that trickflows do have improved rocker geometry make them a great hot street head. I think people lose sight of the fact that they are a true 500 plus hp bolt on street head for around 2k which is something only dreamed of a few years ago.
