If you're still running on the OEM injectors, you're going to max out their duty cycle long before 10K becomes feasible.

Also, I have my doubts about bottom-end oiling if you're going to live a 8K+ all day. And who made those valve retainers? And why aren't you running a higher lift / duration cam?

Get the car on the dyno and see what can be done to improve your midrange before going absolutely mental trying to build a 10K+ street motor.
