    heads are ported (i would say they cant be ported any futher)
    havent got into the bottom end yet but the valvetrain is stock rockers
    rpm limit is 8,000 rpms (wow)
    waiting to get cam specs and see what is in the bottom end
    more to come

    Wow I'm surprised the valvetrain is basically stock. That really shows how durable they are under extreme use.

    Amen to that, but it doesn't surprise me as I have yet to see anyone post up about any serious issues with the stock valvetrain/oil system which so far have been in the 7000-7500 rpm range.
