500 EFI valve adjustment

How do I adjust the valves on a 500 EFI ? It has Crane gold roller rockers. Never had to adjust adjustable rocker arms. Have a few that were louder on one bank than the other.

Thanks

which ever cylinder your adjusting,,bring it up to TDC,adjust by finger to 0 lash,then go 1/2 turn more.lock the allen down while holding the adjusting nut.

run them in firing order, less crankin the crank, make sure the lifters are on the base circle of the cam when lashing

A way to be sure. Both valve covers off. 18436572. When both rockers are moving on 6, 1 is good to go. same with 8-5, 4-7, 3-2.
