Springs/retainers to keep the valves from floating, and pistons/rods so things hold together at higher revs. To make power up high- it's all in the head. Port/polish, cams.

Go fast, Go Cheap
basically make anything that moves lighter/balanced and stronger. It will help in acceleration as well as allow you to raise your rev limiter, which requires programming the ECU. depending on weight savings everything will GO better.

I dont even know why i'm bothering posting. Its all in the valve springs. That'll get you way higher. but its of no use if you dont have any power up there.

Exactamundo, it does no good to spin your engine to 12,000rpms, if no more air/fuel is coming in, or being combusted than at 7200rpms.
