Hi, I'm replacing the head gasket of a 1993 Nissan Maxima and the mechanic book says that I have to replace the head bolts. I was wondering if it's really necessary or not. Thank you for the eventually answer.

Yes. Many engines use "torque-to-yield" bolts that are a one-time-use bolt. They physically stretch when installed to help hold the cylinder head clamped tightly in place. Used head bolts will not hold sufficient tension on the head.

Good practice but not necessary-unless its stretched-
