Ed, firstly, we know that the 5M block can be taken out to 85mm safely. The problem is finding pistons with the correct compression height and gudgeon pin diameter to fit. Datsun L18-20 pistons....remember?  If you want to do a more comprehensive search, go to www.acl.com.au and download their piston catalogue. It has all that shit in there, as well as available overbore size pistons. Go to customer service, then scroll down the tab to catlogues.
As for determining when to bore, you need to measure the bore with an internal micrometer and check for bore taper. This is then checked against the factory manual (which I don't have  ) and a determination can then be made. Also one should look for obvious scores or rust holes in the bore (if it's been sitting around with no head on). The easiest way is to take it to an engine machinist and let them sus it out for you.
By the way keep the 40 thou over pistons.
