The hard and fast number for all 228 MM  flywheels is .970ths
I have a dept gauge with a digital read out that sits next to my flywheel
grinder for this purpose
A vernier caliper can also be used to measure dept

Its common to see flywheels that are out of spec from prevoius incounters
with a mad machinest
suprpising most worked without complant
