The only thing that comes to mind is the amount of material removed. You
can only remove so much before you run out.
If you deck the block, align-bore the crank journals or cam journals,
bore for oversize pistons or anything else the removes metal you will
eventually run out of metal.
If your cylinders don't need boring (no odd shapes, tapers or wear),
then a nice honing and new rings will liven up an older engine. Older
engines can benefit from a valve job, and a fancy cam is always fun,
though you might not think so after you get done tuning the carbs and
ignition for the new cam profile.
Rebuild time is a great time to repaint the engine, and everything else
under the hood. When you are done you'll have an engine that you can
trust, and it should solve any leaks you might have.
And the next time you rebuild a Datsun engine you'll be faster.
