try finding a manual that tell u what lifter is at bdc at TDC on the balancer then u adj about 1/2 the lifters then turn the crank one full turn and do the remaining lifters.. u will need to know the cold feeler gage setting. tighten the rocker down till u have a snug fit when pulling it out. just don't over tighten the rocker, that will equal a bent push rod. i know a motors manual gives u this info.. keep in mind when u fire it up it will click and always have a small clicking. there solid not hyd..
