Just anything that makes contact with the head. Also make sure you don't mix up the head bolts. If I remember correctly, there is a bolt that can only go one way do to the valve cover mounting or ground wire positioning.
What Joe said. If I remember right, the rear driver's side head bolt can be a pain too- lift it up until it's clear of the block, but still below the firewall seam, then rubber-band it to a rocker arm or something to hold it at that position.
