Since when is the trick flow, edelbrock, speedmaster or any other ootb std. rocker head supposed to do anything super impressive!, if I truly wanted to be fast n/a then I would be looking at a different head for sure. None of them are race heads, the trick flow is basically a cnc ported std. port head, and from the sounds of things the bloomer head is a heavily reworked speedmaster. Maybe he does have the secret sauce to make them better than the others but as said already you are just paying for a ported street head.
