What hp and torque am I making?

Not a fan of the speedmaster heads in there OOTB condition. But! If YOU can do the work yourself, that’s great. It’s hard to ignore the “Black Friday Sale” on these heads. Stupid cheap!

I have a set of them from ProMaxx fully CNC ported. At the time of purchase before the bug and inflation that is happening, there cost now of just over 2K represent an excellent bang for the buck. They flow some decent numbers that if you wished, could be expanded on.

Do you have these running in a car or are they a work in progress? Looking for feedback on performance and your application (cam, gear, etc).
I've got a set of the non-CNC MAXX 171 that I'm contemplating sending back for the CNC treatment. Last I checked he would do the upgrade for ~$900. The extra 25-35 cfm above .500 lift should make a pretty good difference on the top end, but because I'm focusing on road course type performance I want to be careful not to kill the low and midrange rpm torque.
