Below is a link to a good article about a CJ intake and cam install. For those wondering I confirmed the baseline number is with the headers so the gain is with the intake and cams. With bolt-ons that's almost 80 HP in total. While a bit expensive you gotta pay to have the ultimate Boss motor. If I did this I'd upgrade the valve springs too.
