Given that 0.05 mm is 1.96" thou in real numbers and that the shims are only supplied in 0.005" thicknesses, it should be OK, however, in checking that be sure that the Cam is Thrust in to the Thrust Plate and also check at both extremes of the Crank Endfloat.
In regards to checking for Crank 'tight spots', that can really only be done first with the Crank only fitted to the Block and then with the Rods / Pistons fitted, but without Rings. If you have the rings fitted all you'll feel is ring drag, which will be it's highest mid-stroke and least at TDC / BDC.
OK cool. I am a metric kid but that all makes sense!
I checked the crank before fitting the rods and pistons and all was well. The stiffness tallies with the mid-stroke explanation so that's reassuring. I guess it will run in a bit.
It's my first foray into engine building so I am being cautious and learning along the way. Thanks for the support.
