Thanks, Strife. I guess I should have mentioned that the the valves were were recently redone, the heads milled, and the rockers put back in different positions, for reasons I explained in a previous thread. Based on info I've gathered so far from a number of very experienced Indy's, MB techs, and particularly someone who's been working exclusively on cams for over 30 yrs, I've concluded that changing rocker positions is not nearly the problem some people have made it out to be.
In addition, I've been led to believe that changing the shims to balance out any differences in the relationships between the rockers and cam lobes will reduce the possibility of valve clatter. So, that's why I started this thread. However, I'm still not quite sure how to calculate the thicknesses of the shims I'll need?
