Good writeup. But the cam section is a little iffy. A more agressive cam profile does not necessarily allow you to rev higher. But upgraded valve springs and titanium retainers might. Camshaft engineering is complicated and an exercise in tradeoffs. Do you want low end grunt/torque bump, or all out top-end power? You can't have both on the same grind/ramp profile.

Porting, polishing, unshrouding valves, "waisted" valve stems are all options for better breathing too.
