Use stock 1970 340 rods in rebuild?

they never break?...LOL
last set was 3 years ago...rods were shotpeened..magged..beams polished...and had ARP Wave lock bolts...5 passes ..had light piston on it too...so yeah..they never never never never break...LOL

40-+ year old rods with how many heat cycles...don't know if they were abused or what in previous life...with a heavy *** piston connected to it....yeah...I made thousands of passes with stock rods until one night going thru the traps...took out the whole side of the engine..and the one above 5 passes....Nope ...not any more..
