Looking to re do my whole valve train and not sher best parts to use. I want to make as much power thruthe head without touching my bottomend. Thnks

 

crower 1mm over sized valves
crower stage 3 cams
crower valve springs and retainers
adjustable cam gears

That should give you some power.
Port and Polish would also really help out, let the engine breath, also some good 4-1 headers, and a nice intake manifold and bigger throttle body.
