Yes, it is if the cyl is round (usually it is close enough to get a
reasonable reading)  Use a piston to push ring down to make sure it is even.
 Amount of taper should be Pi times greater than increase in ring gap, and I
usually measured it (by whatever method) at the top, bottom, and 1/2 & 3/4
ways up.  one advantage of using a ring is you can find the location of the
greatest wear easily. (Usually at the top & second ring locations w/ the
piston near TDC)
