There is no torque on the rocker nuts. The valve train is adjustable and those nuts are the adjusters. Do a Google search on setting valve lash on smallblock chevy. You'll find a wealth of atricles on how to od it.

no, they usualy dont self adjust you have to set the valves, typically to adjust them, tighten nut until until drag on pushrod(while turning the pushrd itself) and then i usually go 3/4 of a turn more

Not self adjusting, they use hydraulic dampening to keep them quiet and eliminate the clearance associated with solid lifters and overhead cams. You need to set the preload on them and that is what the adjuster nuts are for.

For clarity, the '94-newer small blocks had the positive stop with no adjustments. Ford ("big blocks" and mid-'69-newer small blocks), Pontiac, Olds, Buick, Caddy, Dodge, AMC all had positive stop-type (valve stem height is critical) non-adjustable lifters. Chevy was odd man out in this matter.

Did you adjust all the valves at once? On a Chevy V8, you adjust half of the valves in the #1 firing position and the other half at the #6 firing position. Here is an Autozone page that lists which valves to adjust at each position. http://www1.autozone.com/az/cds/en_us/0900823d/80/11/bb/3c/0900823d8011bb3c/repairInfoPages.htm
