I called and had an interesting conversation with Michael at B3racing today and that's the direction I'm going with this project as it's more than just 'a few shims'. Check out his tech article on rocker arm geometry and Jim Miller's page as they go pretty much hand-in-hand. Great info and I'm sure many Chrysler racers and builders here on moparts would benefit from this correcting their geometry as well.
