Dave you come up with some good questions, since i was unaware of any such procedure i "winged it" and must have had unwavering trust in the concentricity ( is that a word? ) of the machine that produced two of the finest camshafts in history.
So i cannot even remember how i went about measuring the gap but i vaguely recall using the small sections of the lobes so the cams must have pointed away from the buckets.
We now need someone else to shed light on the right way to check the valve clearances and i am happy to take notes and put them in the recipe book for next time.
Don't know mate, what was confusing at the time is the markings on the sprockets for in and exhaust valves appeared initially out of alignment, but after thinking about it it made sense and of course all was well, i just expected two straight lines that were parallel and lined up with the top of the heads, they were not straight but the markings lined up fine.
It may be that there is a procedure that still works even when the shaft is a bit worn in the bearing area's and the valve springs have an effect on the pressure on the shaft, i take it that you measured every single valve in the vfr after the adjustments were made, verified they were correct and noted the results down for the future?
Going well Dave!
