Do you mind sharing what you paid Modern to have these CNC'd? Who did you work with? Just curious who to talk to if I give them a call. I assume you ordered the Maxx series head part #9361 or 93615?

I also read some not nice reviews about their turn around time. There are some guys that waited over a year for Bob to get their heads done. How quick was the turn around for you?
