Cool. The shop manual has a similar check. I just tried it and it seems
quite accurate.

Subject: Re: cam timing
OK, a simple way to check with engine together & in the car, if it's a
symetrical lobe cam...
Set #4 (6) inlet & exhaust valve clearance to a big number, .050-.060 is
enough for most profiles. It doesn't matter what the number is, it just has
to be accurate, make sure it's right on the base circle when you set it.
Then turn the engine by hand until the #1 cylinder is at TDC on the
combustion stroke. At that point the #4 (6) exhaust is on the closing ramp &
the inlet is opening & if the cam is set straight up, no advance/retard,
the clearance on #4
(6) valves will be equal. If not, just turn crank slightly until clearance
is equal & note variation from TDC.
