TTY head bolts Torqued once, throw away buy new ones?

[hotballs]

I know they are only $15, but I'm doing some research for a buyer. I used new TTY head bolts on my head installation and drove for maybe 25 miles.

Are those TTY bolts now junk? Could you use them again?

I would say just spend the money to be safe but I wondering what the call is.

TIA

Yes, throw them away. It is the final torque sequence that stretchs the bolt and makes then non-reusable.
