Unless you have a 1/4" torque wrench just snug them with a rachet. I was using a 1/2" torque on the mainfold bolt and sheared off the stud.

Yeah, I think the 1/2" drive had a lot to do with it. Unless something is over 50ft/lb I use a socket and snug it. I had to buy a new stud ($3) and nut extraction set to get it out.
