VVT Solenoids

I've been doing a lot of work on my 2007 Xterra, and I had to remove both of it's VVT Solenoids. When I was reinstalling them I snapped a bolt on each one. I had my torque wrench set to 8 ft pounds. My question is if I have a bolt on each outside holes, is it safe to drive for a few days till my replacement ones come in? Also, when I go to reinstall it, is there anything I should do so the bolts won't snap again?
