    CAUTION:

    Due to the changes in the pushrod clearance holes in the Eagle 5.7L cylinder heads, close attention must be given when installing the pushrod(s) into the tappet(s). Once the pushrod(s) have been installed, use a suitable light to look down through the pushrod hole(s). This will allow you to verify the pushrod(s) are centered properly in the tappet(s) and avoid engine damage. Recheck after the rocker shaft assembly has been installed and tightened to specification.

    CAUTION:

    The longer pushrods are for the exhaust side and the shorter pushrods are for the intake side.

    NOTE:

    Pushrods must be installed in the same order as removed.
