You have an adjustable valvetrain...right?
Fastest, simplest way to adjust valves on a hydraulic-lifter engine THAT ACTUALLY HAS AN ADJUSTMENT AT THE ROCKER ARM:
1. Loosen all rockers so that the pushrods have up-and-down play.
2. Tighten all rockers so the pushrods have NO up-and-down play, but don't tighten beyond that point. (Tighten to "zero lash".) THIS IS CRUCIAL.
3. Turn crankshaft exactly one turn.
4. SOME rockers will be loose. Tighten ONLY the loose rockers until you have zero lash.
5. Tighten ALL rockers "your choice" of preload: Most folks go 1/2 turn, some like more, some like less. Be sure to verify what the lifter manufacturer/reseller specifies for your lifter part number.
6. Put the valve covers on, and have a beer. Say "thank you" to MotorDaddy, who taught me this procedure. You're done.
