Clean the threads clear with a wire wheel,
or a wire brush, light oil, wipe off any dripping
oil, you can use loc-tite on those, or just torque
them down without, I think the factory uses
loc-tite for an extra amount of guarantee that
the bolts don't come loose, more of a warantee
issue, a properly torqued bolt would be hard
pressed to work it's way loose, espessialy on
the head.
