Whether or not Chevy, Ford, Pontiac, Oldsmobile, or 4-6-8 cylinders, Foreign or Domestic follow these directions closely and valve adjustment is very simple. MUST check if the pushrods are bent new or used. Using any piece of glass roll one pushrod at a time across flat surface it will roll smooth, if it is bent you will know it and change if necessary. Heavy wall pushrods must be used for high spring pressures. Time to adjust valves, the most important thing to know is do one cylinder at a time starting at front and working your way around. Rotate engine directions when the exhaust valve starts to open adjust intake valve, when the intake valve opens and start to close adjust exhaust valve. Example When the exhaust valve just starts to open on # 1 Cylinder we will adjust # 1 intake valve by loosening polylock slightly while spinning pushrod until you feel lash in the rocker arm spin polylock down until you feel lash go away and now feel the pushrod snug up a little, ADJUSTING VALVES ON SOLID LIFTER OR ROLLERCAMS The most important thing to know is adjust one cylinder at a time starting at # 1 and work your way around you must rotate engine direction.
