Evan,
I looked up the blueprint specs for the 07 GT500 and the 08 CJ and I don't see the differences that you are talking about. (Specs don't have a GT500 for 08) The valves are the same size. The TB is 2x62mm for both. Compression is only 0.12 less due to a slightly greater deck height. But yes, the cam is smaller in the CJ. Am I looking at a different spec. than you?
Thanks for clarifying...
Fred
