Head bolts

What's the conventional wisdom on replacing head bolts when replacing a head gasket? This is on a 1592 engine bored 0.060 over. The gasket blew between 3 & 4 about 5 years after re-build.

Wow, I never seen one blow like that.
On head bolts there's not much one can do, but clean the bolt & block threads, and check the head bolt washers and the head surface were the washers are compressed. I have seen the washers become dished from so many re-torques. If some are dished you might want to replace them with new hardened head bolt washers.

For what it's worth, I replaced mine with hardened ones just to be safe. Cheap insurance and I figure it distributes the load just a little better.
