    I have the springs and retainers. I've heard not really so good for 10k.
    I don't expect to do much 10k (have done about 9k), but I would really like to upgrade the valves if some are out there.

    Not running 10k just that far till the limiter kicks in.
    He said 9200 or so is find but that most chargers make their power around 8600-8700.
    I figure that is good enough for me.
