    Many aftermarket rockers contribute to early valve float. The only engine that has ever died with me on the dyno died from this. He moved the rockers to his new engine (new dual springs) and the same happened but no PTV action fortunately.

    There isn't really much to find here in the HP dept either, spend your $$ on other proven mods.

    Agreed. Stockers are a great piece. Do the Harlan upgrade if your worried about the needle bearing problem. Your going to gain next to nothing for the price. Save it towards a camshaft swap.
