Please excuse if this is a noob question. Part of measuring the valve clearance is to "feel" the drag on the gauge between the shim and rocker for the openers. On the vertical cylinder, part of the drag is caused by the weight of the rocker. Wouldn't this lead to inaccurate measurements? Wouldn't it make more sense to measure between the cam and rocker? This way the drag being felt is truly only caused by the gap between cam and rocker and not the weight of the rocker?

Check every rocker and record the measurements. Just try to be consistent. By the time you’re done doing them all, you will probably have learned about the” feel “ for yourself, and trust your own judgment on it. By trying different shim gauges , thicker or thinner, until a larger one won’t fit. Make sure the feeler is parallel with the surfaces. As you move it around, you’ll notice when it has the least drag when everything is aligned. Try it. After a while you will realize that .001” down from the gauge that won’t go in is an accurate enough measurement. When you’re done , you will Know they were all way closer than when you started. I rotate the motor a few times when I’m done , just to verify .
