I put my Raceware studs in one at a time on my 1.9D engine. I pulled one bolt at a time, 
following the Bentley tightening sequence, ran a tap on an extension down the hole, then 
lubed and screwed the stud in place:

Same process as Loren mentions. Then I think I took that stud up to the first torque spec. 
Then repeated for the rest of the studs and then went over all in sequence rechecking the 
first, then second and final torque specs. I think I drained the oil and coolant the night 
before. I think that was 8-9 yrs. ago, no leaks or any other issues since. I do recall 
that torquing those studs was so easy compared to watching the guy that did the TTY bolts 
that did the final torque in my old '81.

Never have done a single-at-a-time installation though, always a full set with the head off.  The sealant they recommend tends to lightly hold them.  With the fine thread nuts, the studs don't tend to want to spin so it's simply a matter of having them in enough to get enough "meat" to hold the stud and not pull out.  Not too critical I would think.
