Dyno #'s with Trickflow Heads

So I finally got my trickflow 190 powerport heads installed & got the car on the dyno. My previous heads were a set of EQ magnum heads that were done up by IMM. Very disappointing results, car only gained 2 rwhp and 6 rwtq. Guess the EQ heads were the real deal, should have left well enough alone. Car made 292 rwhp and 311 rwtq @ 5500rpm 36 degree total timing & AFR 12.85.
