Bolt #11 goes into the water jacket - use either LocTite PST or #545 (REALLY REALLY good pipe dope or Hydraulic sealant) or a quality plumber's pipe dope will work as well. Don't use teflon tape for this, last time, I used Harvey's Teflon Pipe Dope, since I couldn't find by bottle of 545 (but all three will work.)
If you are going to put anything on the threads of the other bolts, I suggest using never-seez instead of LocTite - once you torque the bolts, they don't go anywhere, and the ends of those bolts get pretty warm...
