Wow, this is alot more complicated then I thought it would be. I have adjusted my fair share of valves (never mopar, mostly 4cyl engines and small 4 strokes) why did they make it so complicated.
No it's not. Easy. Warm it up. While it's warming, think about what you'll do so you don't waste a bunch of time as the engine cools. Get the valve cover ready to come off, pull loose wiring harness, vacuum lines, etc as much as you can.
Shut off engine when warmed up and pull the VC
Now watch the no1 exhaust valve. Bump the starter until the valve moves off "closed." Stop and adjust the intake.
Bump the engine until the intake comes "up and over" full open, and is nearly closed. Adjust the exhaust.
Move onto no2, .......rinse.....repeat.
I use whatever feeler "you want" and another a couple of thousands larger. You should get the target one in, develop a "feel" and NOT get the larger "no go" in.
