Not really a apples to apples comparison, your head is a fully ported Speedmaster bare head, how about taking a bare Trickflow head and giving it the same level of porting.

Boosted kinda did that. He sent his trickflow heads out and had them ported a little and larger valves put in. I don't remember what he was running e.t. after but is was somewhere in the low 50s maybe even the 40s. I am personally running high 50s - low 60s with out of the box trickflow's.
