    Would it be any good or basicly the same as having ph3s/708s?

    Obviously its been done by that chap. But as he rightly says they are not timed up to their full potential.

    Theoretically, they only be timed to same as ph3s "lift" if that makes sense because thats the limit, but duration is longer so that again will hold it back.

    Stick with the ph3s on standard pistons imo. Running ph4s would be worse.
