I always like to take my time when adjusting valves...this is how I do it:
Plugs out, coil wire disconnected, rotate engine by hand, clockwise of
course
When #6 intake is fully open, set lash on #1 intake
turn engine by hand, watching for #2 to fully open, then set lash on #5
repeat through the rest of the firing order :
#4 open, lash #3
#1 open, lash #6
#5 open, lash #2
#3 open, lash #4
The valves open in the above sequence, so only a little rotation is needed.
I do this once for the intakes, then once for exhaust, to avoid changing
feeler gauge
blades. It takes two revolutions like this.
Don't try adjusting valves on a running engine if using a performance
camshaft, it's next to impossible to get accurate settings. Even on a
stocker it's messy, oil seems to get all over everything.
