So I am in the middle of my head swap and just opened my box of bolts from GM. I am missing one of the long head bolts.

Any ideas on what to do?
Can I reuse one of my old ones? If so, what location would it be under the least amount of stress and less likely to fail?

 

You are not supposed to re-use factory head bolts period. I would contact the vendor that sold you the set & get a new one.

 

yea problem is that the car is my daily driver and I need it to get to work on monday. I just called the local auto parts store and they have a set in stock, SO it will use one of those bolts.
I got the GM bolts from byunspeed. Certainly not their fault that GM left a bolt out, but hopefully then can give me a refund for the bolt set, since I have to buy another one..
