My guess is either 1) you had a weak valve spring and because of this, the valve did not shut quick enough for the rpm he was revving. (as in passing another vihicle)
or 2) the valve stuck open for a split second due to carbon.

B) The lifters may have no oil in them and be bottomed as soon as the lash is gone during this static madness.
Am I correct?
It is impossible to adjust the valves without rotating the engine as you go. Yes he is crasy! Don't start the engine.
Many will be too tight in this method, and many will be too loose. I see bent valves. Do not adjust your valves till they bottom out, rather adjust them to the point where the push rod makes contact with both the rocker and the lifter. You will feel an ever so slight restriction as you turn the push rod to get the feel of things.

I would go with half a turn after I feel the push rod contacting the lifter and the rocker.
There is a sequence to do this in. If you need that, please ask. In other words, you need to rotate the engine to eight different positions to adjust 16 valves.
