Main bearing....main bearing oil clearance-standard=0.018-0.036mm [0.0007-0.0014in].

Maximum...0.10mm [0.004in].

Big end con rod oil clearance....0.028-0.068mm [0.0011-0.0027in]

Maximum...0.10mm [0.004in]

Side clearance....0.110mm-0.262mm [0.0043-0.0103in]

The NA6 is a non interference engine as it sits, you'd have to do a fair bit of head grinding for that to change methinks.

It doesnt give that info other than the max amount to grind the head is 0.20mm [0.008in] which is also the max grind for the block if that helps.
