i still use the 1/6th turn method but it is only the best while the condition of the valve tip and tappet pad are poor. if we get to the stage where those two contact surfaces are square, i'm sure i will pick up the feeler gauges again!
but most pre '04s in a bad way and i would never use a feeler gausge. i can't justify the length of time it takes to make a fool of myself.
don't forget your axial clearance, that needs sorting with those that don't bother checking running 1mm axial float.
