Trick Flow 440 heads, The Real Deal?

We have an update as well with the latest BBM with these heads. Combo is as follows

400/500
11.25 to 1
RPM Dual plane intake untouched just bolted it on
Proform 850 carb, no spacers
Lunati 255/263 solid roller cam, .600" lift
Trick Flow 240 heads untouched
Hughes roller rockers
It ended up making 667HP and 681TQ

Pretty tame combo, made for street strip use.
