Dyno #'s with Trickflow Heads

I have 11/1 comp and it is a 5 speed manual! Yes I requested a wider lobe sep to calm it down a bit because it is a manual and I am 66 years old so wanted a nice car to drive. Yes the chassis dyno shows a drop in torque but it doesn't feel like it on the road,just smoother and better behaved. Are you saying my sixty foots will blow out? Remember I have a manual and best results before were dropping the clutch at a low twelve to fifteen hundred revs but I can experiment and drop the clutch at a much higher revs to make use of the power band in the cam.
