Just like the title says. I just bolted some heads down and I am suspect of one head possibly being warped. I thought it was getting hung up some on the dowls but I need to recheck it for peace of mind. Can I reuse the same bolts since they have never been heat cycled? I usually use ARP bolts and have never ran into this problem before, hense the dumb question.

No, TTY bolts are made to stretch in betweeen passes of torque applied to them, although they may have not been heat cylcled they have stretched. I would reccommend new bolts...

No. Heat cycling doesn't matter with TTY head bolts. You must buy new ones the moment you torque them and remove them.

The key word in TTY is yield...you've induced failure in the bolt, and they need to be replaced.

what must one do with used head bolts? are they just trash or can they be used for anything at all??

Mock up? Show pieces? Recycled for the metals?

Get a set of ARP bolts or studs and never buy them again.

Thanks guys. I guess this car is going to sit in my garage for another two days. I use ARP's but I can't dictate what the customer buys. Plus this car is supposed to be as stock looking as possible from all angles.

Randy. What kind of power on motor are you making? I just screwed together a 416. Our set up's are actually not that similar but I would like to know how your combo does compared to mine.
