Here's a procedure that an engine machinist showed me a few years ago and it
works well.
A. INTAKE VALVES:
Turn the engine by hand until the #1 exhaust valve just begins to open.
Adjust the #1 intake valve to .008" cold or .006" hot*. Then rotate the
crank 60 degrees until #5 exhaust begins to open and adjust the #5 intake
valve. Repeat this in the firing order; 1,5,3,6,2,4.
B. EXHAUST VALVES:
Turn the engine by hand until the #1 intake valve has opened and closed.
Adjust the #1 exhaust valve to .013" cold or .016" hot*. Then rotate the
crank 60 degrees until #5 intake valve has just closed and adjust the #5
exhaust valve. Repeat this in the firing order; 1,5,3,6,2,4.
* Adjustment specs are for the Chev 235.

No, two different engines. The Loadmaster was an option in the larger
trucks.
