    You don't have to change the head bolts on a 6.2
    The 5.7 had the Torque to yeild bolts, but the 6.2 has reusable bolts.
    At least that is what I read.
    If I am wrong I am sure someone will chime in /forums/images/graemlins/smile.gif

    The 6.2 bolts are TTY as well, you should be able to get a set of fel-pro bolts for around 18 bucks a set at autozone.

    I've seen (heard) a few 6.2s that were "knockers". My own Jimmy started doing the same thing shortly after I bought it. I feared the worse, even had the oil checked for bearing metals - nothing found. Kennedy Diesel told me alot of the noise can be attributed to sticky lifters. So I ran 40/60 blend of 15W40 and ATF in the motor, let her run at idle and low speed for almost an hour. Changed the oil & filter (back to 15W40), presto knocking gone. 'Haven't heard it since. /forums/images/graemlins/thumb.gif

    Hey give it a try, can't hurt - much /forums/images/graemlins/grin.gif
