Rick, good points about how a new cam will really "wake up" those new heads. But even the heads alone should provide a nice boost in power, do it in "stages" if thats what the funding dictates.

I'm curious as to what "exhaust" modifications were suggested for the AFR heads? I've seen applications on the 302 where it was straight up and down remove and replace, done!

Myself I prefer the AFR165's for a 302, all though the Twisted Wedge do flow more CFM, it's happens at the high end of the rpm range. I suspect AFR165 offers more "over all streetability" up to the 5800-6000 rpm range.

The cam can be swapped out later without pulling the heads. If I were doing it I would consider going with a higher ratio rocker arm to increase valve lift. A "poor mans" way to a bigger cam if you will. Careful using a bigger cam AND a bigger rocker ratio, valve clearance issues may come up.
