Some bolts are longer than the others.
So you'll need to keep them in order of removal for an easier time of re-installing them.
You can use a piece of cardboard or an old pizza box to keep from mixing up the primary cover screws (or cam cover).

• Keeping the bolts in order as you take them off saves time and headache of remembering which length goes where.
