I would not suggest this. I am with Todd Marsh. I had this exact situation, and I would not attempt it. I asked one of the best in the business to do it, Weston Machine, and they wouldnt either. It went back to Indy. This can go bad very quickly.
I think that is good advice for any backyard guy but based on what I know about Indy, I doubt that they have any sort of "sophisticated" process for drilling these holes. I'm pretty sure I could come up with a method for drilling the holes that would work as well as anything Indy has. If someone who has toured the Indy machine shop wants to weigh in with a description of the Indy "hi tech" process I'm all ears.
