AFR Heads
Well following up on this thread, I have a pair of the new AFR heads on my bench currently. They are not the speedmaster casting, they look nearly identical to the promaxx heads, although I do not know for certain which casting company does them. A few small differences I noticed is that they have 8mm guides, a better valve job and cnc blended bowls. That's all I see so far.
