Edelbrck vs Trick Flow

Are you talking about trap speeds? The speedmaster heads were untouched. I had bought them bare, non CNC and just threw some some valves I hand lapped and some springs. The trick-flows are out of the box. Same .590 purple shaft, m1 single plane and proform 850, 4.56 Dana with 28x10.50 pro bracket radials. 8" coan converter that flashes at 4800.
