Default LS7 Rods - re-use

I can not find any confirmation within the GM manual for re-use of the LS7 rod bolts. I have some rods with only a few hours on them I want to remove and re-install. Do I need new rod bolts because they are TTY? Usually the manual is real clear about this but I can not find it. Also if I replace the bolts do I need to re-machine the bog end like the old days?

Thanks!

I dont know anything about the LS7 rods, but if the bolts are TTY, get new ones.

Yes, you need to replace them. Size your bearings with the old bolts and install new ones for final assembly. The LS7 rod bolt can only be torqued 3 times. No machining will be necessary.
