valve adjustment for 250 inline 6 cylinder GM 73 chevy c10

Hello,

From GM service manual:

 

HYDRAULIC LIFTER ADJUSTMENT

 

Rotate engine until ignition rotor is at #1

Adjust INTAKE valves 1, 2, and 4 and EXHAUST valves 1, 3, and 5 by:

Backing off rocker arm nut until lash is felt, then tighten nut until all lash is removed, then tighten ONE full turn

Next, rotate motor until ignition rotor is at #6

Adjust INTAKE valves 3, 5, and 6 and EXHAUST valves 2, 4, and 6 using the same procedure above

 

Thanks, Dave
