Twin Plug DIY?

Anyone out there do their own head machining for a twin plug mod? As I look at the vast expense of my engine project, knocking off $500 for the twin plug machine work would be nice. I don't have a twin plugged head for reference and I'm a bit apprehensive about going off pictures so I'm looking for someone that's done it and that's not worried about giving away their trade secrets.
