I obsessively use anti-seize on *nearly all* external fasteners, but never
on any fastener that has direct access to the oil supply.  In general, I
can't think of a downside to using anti-seize as a default strategy.  I'm
also sort of obsessive about using Permatex Hylomar on most gasket
applications.  The stuff remains pliable forever, and I used it quite
liberally when I recently R&R'd my H2O pump.
