StarTech:
I always set OHV at the minimum clearance specs as they tend to open up due to wear. I also adjust using an alternate method
What is your alternate method?
One valve at a time that way I don't have hunt a measuring tool or remove the spark plug(s). Just sure the rocker being adjust is the one that the valve is fully closed. I know it is different but I am set in my ways from the auto industry.
