valve adjustment
Yes you can
While the engine is hot and idling, and valve cover off, select the correct feeler gauge 10 for intake 15 for exhaust and slide it between the rocker and the valve. Put a closed end wrench on the adjuster nut and tighten until it gets hard to get the feeler gauge in there and then back off a little.
I do it all the time, you may want to put an old towel on your fender well and try not to rev the engine with the valve cover off.
Trust me this is a much much faster way to do this.
