what he said, they are torque to yield... so once you torque them down they stretch beyond yield limit and should be discarded after first use

do not reuese them. If you plan to be in there very much put studs in and be done with it.

I say go for it.. use the gaskets, too.

jk, yea definately not, however I know someone who actually did reuse the stock bolts and his engine went a long time on a 175 shot before popping a headgasket.

No you cannot reuse them

To use stock head bolts you need both a torque wrench and a torque angle gauge. I have this one and it worked extremely well when i swapped the head gaskets on my Duramax, 36 bolts that had to be torque down 4 times to about 150lb.

No, the stockers are torque to yeild and a one time use. Replace them.
