I have measured/inspected 3 x K-series cranks and not one of them had suffered from eccessive end float. Big end and/or main bearing scoring yes, but not end float issues.
Are the digits stamped on the crank corresponding with the markings on the crankcase, could it have been changed at some point in its life?

In each case I used feeler gauges, althought the dial gauge method you used should be more accurate than feelers anyway.
Now, I cant recall if I bolted the complete engine assemblies together to carry out the measurement, perhaps you should bolt the complete assembly together, and check again.
