from a certain year the bolts are stretch-to -torque type. That means the bolts stretch out under the torque (probably that last quarter turn). I don't have my workshop manual here, so I can't say which year exactly. The general rule is if the bolts are all equally long, you can reuse them. More than once too. If the bolts get tired, they'll lose their elasticity. If one is markedly longer, take it out and replace.
From my experience, more important than the bolts (within limits, of course) is having a good flat head. I changed heads more than once, and the only time I was satisfied with the outcome was when I had the chance to surface the head. I was especially amazed with the immediate and big improvement in performance. It was an 8v engine to be sure and after the change I found it better than my neighbour's 16v. So that's my main advice: make sure your head is straight and flat, AND clean the surfaces very, very, very well.
Good luck! It's really an easy job, when you get the hang of it.
