OK- - - -found it! That search function would drive a saint to alcoholism!
Here's an alternative valve adjust method I've used for over 40 years:
Companion cylinder valve adjustment
Turn engine by hand until you observe #6 exhaust valve closing. Continue turning until #6 intake begins to open. (Called "rocking", valves moving in both directions at once) This happens at the top of the exhaust stroke, with the piston at, or near TDC. #1 cylinder, both valves, can be adjusted at this point. Turn until #2 cylinder rocks, adjust #5. (Each time the engine turns 120 degrees, another cylinder will be at TDC, ready to adjust). Turn until #4 rocks, adjust #3. Next 120 degrees, #1 will rock, adjust #6. Rock #5, adjust #2. Rock #3, adjust #4. All 12 valves can be accurately adjusted in 2 turns of a stopped engine, hot or cold, and no oil spilling!
This works on any engine with an even number of cylinders. Easy way to remember which ones to rock/adjust: Write down half the firing order, then write other half underneath it: Chevy 6:
1 5 3
6 2 4
1 & 6 are companion cylinders- - -rock one, adjust the other. Same with 2 & 5, and 3 & 4. Quick, easy, and it works!
For an initial startup, don't worry about using the feeler gauge. When both valves are in the "ready to adjust" position, loosen the lock nuts on both rocker arms, gently turn the adjuster clockwise until all the clearance is removed, then back up the adjusting screw 1/4 turn, and snug the lock nut. That puts just enough clearance between the rocker arm and the valve stem to make sure the valve gets fully closed.
Each cylinder MUST be at the top of the compression stroke before trying to adjust the valves on that cylinder. Call me if you wish, and I'll walk you through a quick valve adjustment.
