Hi
At risk of stating the obvious, put each piston back in the bore it came from and with the small end bolt head facing the same way it was when removed. Keep the rings on the pistons, they are fragile and removal always risks breakage. Not sure how you can get a loose big end bolt, they are supposed to have castellated nuts with split pins or modern nyloc nuts. I would suggest a torque of 20 to 25 foot-pounds with dry threads but opinions vary on this. Have a good check for anything else loose or incorrect.
If you have stripped this far, a clean up of any carbon and a light valve grind (lap) is probably worthwhile.
If the rings do need changing at some time in the future, the knowledge you gained during this strip down will speed things up !
