No seriously, you should NEVER re-use head bolts,

Well that is correct,,, to some degree!!!!
As a heavy line mechanic for several dealerships through out the 70's/80's, (Ford,Pontiac,AMC/Jeep,Chevy) The only dealership that required you to use new bolts on a head pull was Ford. That was only on the bolts that torqued higher than 65psi. On the most part it is a good idea to change them after they are 5 years old or torqued to a high rate. Keep in mind the stress on the bolt head and threads are the issue to include the elasticity of the bolt body. On the other hand if you stretch the bolt threads that means more than likely the block threads are stretched too [img]images/graemlins/grin.gif[/img].
