Ordinarily and with no damage or reason to suspect they've been taken beyond normal operating conditions,  they are reusable and most engine builds don't replace.

They are torqued during installation within their elasticity limits,  so not taken through "yeald" as a stretched bolt application does.

13.0 to 15.9 lbs/ft rating from Honda manual.

Welcome to the mad world of the SOHC. If they are OEM they can be reused as long as they have not been over torqued  ;)

Welcome. We have a thriving set of PRR owners here. I'm sure they will be along soon.

Had one myself for a while:

What brought it home for me about re-using con-rod bolts is Honda  tell you to Plastigage the bearings which involve torqing up the nuts and then disassembly possibly a couple of times so technically on final re-assembly they are used.
