I done my recently and used the same bolts as before, did you have your flywheel skimmed or refaced? and are you running a new ap paddle?
if its the same one you had before then just check that there is no glazing to the face of the flywheel and get a metal straight edge to check that the flywheel is flat, also check the condition of the cover plate for glazing and warping it will look a bit like a worn brake disc.
