    The 487 and 487X were good for there time. Still nothing close to a Vortec head, or anything aftermarket.

    just need to have them machined. i believe they can only take up too a .460 lift stock. comp cams sells a tool you can chuck up in an electric drill and do it yourself if you feel the urge :wink:

    We completely re-machine the head to accept whatever cam lift we are using, guide and spring pocket.

    Is it worth machining vortec heads to accomodate lift above .500'' ? I've read that they don't flow any better past .500'' lift, is that true?
    This wouldn't have happened if only you had been paying attention!

    Yes it is worth it if this is what you have to use, or your class rules mandate it. Other wise aftermarket heads are a much better solution.
