With those heads and intake port velocity will be poor for low end hp and torq. Will be great for a high RPM motor and should make good power up top. Pretty much the same combo I had except .030. Made 342hp and was good for mid 12's@110 with a 4.10 gear. I had a NX274HR cam but never sprayed the motor. Cam specs were 224/236 @.50 .555/.570. It bucked a little bit below 2000 RPM,.. definitely wasnt very happy below 2500. But from 4000 - 6500 RPM it pulled pretty good.

I think with a little less cam it could make a decent daily driver,.. but low and mid range wont be as good with smaller heads.
