From Stu: Well, I've been doing this for a couple of years to dial in the ICL on these hemi cams because nothing else was available. No more nasty looking Stu made bushings and sprockets. Crower who grinds all the Inertia cams has come out with a kit that allows you to adjust your ICL. The kit comes with the pre made bushings to advance or retard your cam 2, 4 or 6 degrees. Inertia is selling these kits for $165 which is a pretty decent deal since the stock mopar timing set goes for around $100 and this gives you some adjustability.
