I agree as well. Aside from port matching, cleaning up and deburring the 'rough edges' true blueprinting these engines is a bit of a moot point.
As for what the ideal torelances are supposed to be I guess the only thing you could do is see what the ideal tolerances in other good quality 2 strokes (Morini, Honda etc?) of comparable size typically are and use that as a benchmark. But by the time you go to all that trouble machining, fitting, etc you might as well get a better quaility 2 stroker to start with.
