Bolt question

One of my head bolts is streched but the others seem fine. Is this something that I can replace just one or should I do a whole head or both heads? The other head is already torqued down with a new gasket. Could this be a symptom of a bigger problem? There was a stuck valve and some bent rods on this side and they have all been replaced. The only things not replaced are the block, pistons, and crank. Thanks for the help!

You can just replace the one bolt.

I bit the bullet and bought a set of ARP from Summit. So much for the cheap route. Would switching one bolt at a time on the head thats already torqued keep the gasket intact?

I think that you would be better off using half the set on the one side and leave the other side alone .
If this is an Olds 350 , O'Reilly's has OEM bolts for $2.49 . If you can return the ARP's .
