If you don’t have the intake on yet, it’s easy. Just rotate the engine until the lifter you’re working on is on the base circle of the cam (base circle is opposite the highest lift point) then turn the adjusting but until you just feel done drag trying to rotate the pushrod between your fingertips. Then tighten the adjusting but 1/2 turn, and tighten the lock screw. Repeat the procedure on the other 15 lifters.

if the intake is on, rotate the engine by hand in the normal direction. Stop it exactly TDC on #1. Take the firing order, split it in half and orient the numbers with each half over the other. For example. 18436572 would be
1843
6572

each cylinders in the vertical column are companion cylinders, meaning the are at TDC at the same time. Adjust cylinder 1 and 6, then rotate the engine in the normal direction EXACTLY 90*, adjust 8 and 5, rotate 90*, then adjust 4 and 7, rotate another 90, then adjust the lady 2 which is 3 and 2. You just adjusted all 16 lifter with one turn of the crank.

Get you engine at tdc on #1 and adj ext values 1 3 4 and 8...then adjust intake valves 1 2 5 and 7......get #6 to tdc and adj ext valves 2 5 67 and int valves 3468.

Using this method you will only turn the engine twice. After final adj i work recommend using poly locks
