It looks like I just need to machine down the existing rocker stands and I can reuse three of the existing drilled and tapped holes. I'll have to drill and tap another four holes for the rocker shaft stand. Jesel faxed me a drawing showing where the holes have to go but Indy hasn't provided me with info on how far to machine the stands down.

If I can't reuse the existing holes then it gets a lot harder. At that point I might be better off selling the heads unmodified and buying new heads that are already drilled and tapped for Jesel stands. I guess that is the big question of the day. So far I haven't figured out a way to answer that question without just going for it and machining the stands down. Maybe I'll try to take some dimensions first and put them into the CAD system to see what kicks out.
