I thought later engines had hydraulic lifters, but here you go: Allpar

pull the plugs/dist cap/wires & whichever cyl the rotor is on set that cyls' valves. Grab the fan belt to shorten/tighten it with your left hand and grab the fan with your right hand & turn the eng. On the intakes (.010") set em till a .011" feeler gauge has a slight drag and a .009" gauge has no drag (hold the blade square). On the exhausts (.020") adj till a .021" gauge has a slight drag and a .019" gauge has no drag. I think '80/'81 they went to hyd

This is NOT the way to set valves. You do NOT set valves with teh cylinder at TDC.
Use the EOIC method, which means
Turn the engine until the EXHAUST valve just starts to OPEN and adjust the intake on that cylinder
Turn the engine until the INTAKE opens and is nearly CLOSED and adjust the exhaust on that cylinder. This insures that the lifter is on the back side of the cam.
The EOIC method works on anything from a Briggs to a Pratt and Whitney.
On a V8, Mopar has a handy chart for every 90* of crank rotation. You could write up your own for a /6 which would have to be for every 120* of crank rotation
The V8 chart
Use a feeler for "what you want" the lash to be, and one .002" or so larger as a "no go." Be sure to get the feeler in "straight" IE not up or down from the "easy" way to slide in.

NOT needed on a stock cam TDC firing is just fine for stock and near stock! Why do people try to complicate things for a guy????

I always perfered to do adjust the valves with the engine running, idle lowered to 500rpm or so. Grab a 3/8" box wrench and the .010" feeler guage for the intake and a .020" for the exhaust. Use some shop rags and drape over the plug wires/distributer/fuel pump to make clean up of any oil splash easier. You really don't want the valves to cool in the time it takes to turn the engine over by hand... Keep them hot.

Must have done hundreds this way "back in the day" when I worked at the dealership. No one liked upselling valve adjustments on a slanty and I always made good time =)

Last time I set a '80 slant was when the valve started to open I reversed it then set the gap. You catch it just before it starts running up the ramp on the lobe. Of course hot.
Brakleen and a rag. I clean and dry the spring retainer. Then I mark them with a permanent Sharpie marker. I and E. Saves confusion, and it is permanent! Especially if you want to set while running.
