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 a larger intakes port than most ootb intake 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.
