    i would not go above 8600 with a stock motor.
    i was told that the stock valves will float at 8600.
    you should be pretty safe if you keep the rpms under 8550.

    If you see a lot of 8k rpm I would recommend upgrading the valves train.
    Compared to a motor or just head this is a cheap upgrade.
