Head bolts are placed under tremendous stress and can be stretched. They should be replaced when replacing the head gasket.

Old thread, but there's some banter regarding re-use (or not) of the head bolts starting on page 2. I would always replace with new.

Bolts for the Lincoln LS 3.9 are apparently the same part but cheaper.
