273 cam selection on Desktop Dyno

I don't have any port specs. I just chose pocket ported wedge heads with stock valve size from the dropdown box. I tried the Voodo 60400 and a Comp
number I didn't write down. I could get more HP and torque at a lower RPM
with a stock spec solid lifter cam than either of the hydraulics. Headers seem
to be the best improvement if I decide to install them and a stock spec roller cam is also a nice improvement but lots of $$$$/HP. toolman
