Off-season engine freshen

Yeah it runs great! It smokes a little when I leave, the bottom end has been together for quite awhile though. I went through the heads in the middle of the year, new valves, springs, locks, retainers, pushrods, and new rockers. When I had the heads off I noticed a small groove in 1 cylinder so I figured it would get a bore and hone, new pistons, rings, bearings and mag the crank. I have rebuilt lifters to put in also. Also ill put in a fresh trans and send the converter in for freshening. At what point are people replacing rods and or rod bolts?
