Long story short I bought a LLY very cheap with a serious knock. I took a bit of a gamble and was hopeful it just trashed the crank or maybe a rod or two, but turns out it damaged a main journal. Line boring and billet caps was out of the question so I pulled the plug on the motor (I parted everything out and did really well) Then I went hunting for a running engine and got a smashed LBZ.

The question is, to my surprise the engine had ARP studs installed when I bought it and I held on to them for my new LBZ. I understand they are not torque to yield but should I have any concern using them? I'm sure they are fine just not knowing the history of them or the motor made me second guess myself

you should be fine. ARP has some documents showing how to test/measure them to see if they've stretched
