Unlike many other brands, the 350 Chevy has independently adjustable rockers. From the #1 TDC position, you can adjust 1,2,5&7 intakes, and 1,3,4&8 exhausts. Rotate the engine one revolution for #6 TDC, and do the rest.
When adjusting the rockers, tighten the nut until all backlash is removed. Then tighten an additional 1/4-1/2 turn. This is for hydraulic lifters. For solid lifters, refer to the cam card for the backlash setting cold, and use a feeler gage between the rocker and valve stem to tighten the nut until the feeler gage just slides through.
There are no torque specs for a 350 Chevy. Follow the valve adjustment instructions in any repair manual for any small block Chevy.

First make sure the cam is turned so that the lifter is on the base circle of the cam, then tighten the nut until there is no backlash plus a half-turn extra.
