2.5 Exhaust Manifold Bolts

[Zenobian_84]

Going to be replacing my EMG within the next few days; would be today, but I don't have a torque wrench readily available, and won't until probably Thursday.. :fs1:

 

I'm missing one bolt for sure, maybe more. I know the replacement bolts should grade 8, but is there other things I need besides bolts and washers? I've heard of there being "studs" there too, or maybe people install studs to get the bolts out easier without them getting sheared or broken off. If that's the case, should every bolt have a "stud"? Or can I just use the bolts and washers, without studs.

 

Sorry for the newbie questions, but I've never really dealt with this sort of problem so far with my mechanical prowess. :(
