Yes some extremely high lift cams once the VTEC kicks in is what you need to make power up at that high RPM. You should have the max cam lift your engine will allow before the valves would come in contact with the pistons and trust me you don't want that to happen at 10,000 rpm. Also make sure to upgrade the valvesprings to prevent valve float at that high an engine speed. You may also want to have lightened flywheel just to help it rev better. What some people don't understand is that engine power doesn't really have as much to do with an engine's ability to rev or how much displacement it has as they would think. The limiting factor in an engine's power is the cams, valves, and essentially efficiency of the head flow because a large displacement engine with poor headflow is like having a marathon runner breathing through a straw. This is why VTEC has the ability to allow our relatively small displacement engines, more along the lines of the Honda 4-cyl engines, to make more power than thought possible up in the higher RPMs. If you build the engine internals to handle high stress ie. balance, blueprint, shot-peen, and then get lighter pistons and forged everything, and have the computer delete your rev limit sure your engine will rev to 10,000 rpm easily maybe even higher but you will not make much additional power after 7-8K unless you have major headwork done to supply the needed air flow at those engine speeds.
