Thank you great stuff!
From looking at your CNC ported Speedmasters (just eyeballing of course) would you say that they would by the looks of them flow a little better than a good port job on a stock head?
Imo besides lighter weight, the best thing about an aftermarket aluminum head is that they're already little over halfway there when it comes to material removed or how much porting needs to be done to get the numbers everyone considers "good".
No guide kink, guide half the size to begin with, already more cross section, ssr wall bulge/hump non existant, straight wall more straight, tubed head bolt holes as a result. Its work, but a lot less/time.
