Default 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.

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.
