Trick Flow SBM Heads

I realized when I swapped mine over from the CNC speedmaster heads to the trickflows, I didn't change anything but the head gasket thickness to keep the compression the same. Same everything else, even same tires.

seems like a HUGE jump to gain 6 tenths from a CNC head to the Trick Flows.
Thats probably 80 horsepower, or more. Thats tons.
I personally have yet to see any more than pretty much a push from ported eddies. Not doubting your results, but they seem an outlier.
That means that a guy like Flyfish should expect to run 9.70’s if he took his eddies off and put trick flows on...
Unless the CNC job on those knockoff heads was extremely lacking
