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.
