Yes, you need a new bolt. I'm not exactly sure why, but every how-to and even a GM LS1 shop book I have handy says NOT to reuse it.

Never reuse the Balancer bolt. It is "torque to yield" which means it is "stretched" the right amount to maintain constant pressure.

Same for the head bolts.

GM head bolts are $50, ARP studs are about $250, ONLY reason why i got them is because i know ill be taking my heads off a couple of times and also that im going to be spraying in the future.
