Should I Mess with my Crank Pulley Bolts?

[techguy512]

Heard lots of horror stories about sheared bolts at the crank pulley.

I'm going to have my radiator and condenser out this weekend, and I'm
planning to replace all my drive belts, etc. Should I do anything about the
six bolts at the crank pulley? Here are the options as I see them:

1) replace 6 bolts on principle
2) remove, inspect, locktite and retorque the 6 bolts
3) retorque only
4) none of the above, but something
5) nothing

Appreciate any input.
