How can I tell if the bolts can be reused? ZZP sells some so I figure there is a possibility mine are reusable. The have a KY or KX on them can't remember which one.

Torque to yield bolts should not be reused right? This set from zzp are TTY or am I reading it wrong?

Factory 3800 Series 2 and 3 rocker arm bolts are torque to yield and you should NOT reuse them.

Yellow Terra includes off-the-shelf socket head cap screws (you can get them at the hardware store) with their rocker arms which are grade 8 and work fine in this application if torqued to 24 ft/lbs. I've used such bolts on stock rocker arms without problems. It is a good idea to apply red Loctite to the threads of the rocker arm bolts prior to installation.

If you prefer to use new GM rocker bolts, follow factory torque specification on those: 11 ft/lbs + 90 deg.

Zzp reusable bolts are Allen key socket head. If your bolts are 6 point standard bolts like those in the link you posted, I would not reuse them.

FYI: Allen key socket head = socket head cap screws.
