[b]Summary, 1st cut[/b]

This thread achieves my "print & file" threshold. Thanks for all the responses. Now, for us "end-users" who need an exec summary, here's my glean:

Bore -- Most available bore kits provide expected benefits of higher displacement/compression, but on the XR4/6, they also realize higher, more desireable port velocity, even with smaller bore kits. Caution is warranted with bore kits leaving thin cylinder walls.

Cam -- Higher lift and/or longer duration cams may provide benefits, however, longer duration cams "synergize" with larger bores further exploiting related port velocity improvements. High lift cams stress valve train components and compromise longevity. Longer duration cams  stress less, if at all. 
Cam choice is stock (little or no "con", other than price) or aftermarket comprising: hard-weld/re-grind  (wear/rockers need consideration) or re-grind/without added material (better wear, but hard rockers still recommended).
