We've always used a stud remover/installer, til the other day. Dad discovered something that's really the trick. If you can get one of the tall "connector nuts", like contractors use to tie threaded rod together, in the right size for your job, then your set. Simply thread a bolt about 1/2 the length of the nut in one end and thread the stud in the other, making sure the bolt and stud meet in the middle. All you have to do then is tighten on the bolt just like you would any other bolt, and the stud will screw right in. When your tight all you have to do is loosen the bolt and the bolt/nut assembly will screw right off. Dad put in 12 1/2 inch studs the other day in less than 5 minutes doing it this way. The good thing about this is all it takes is one wrench that fits the head of the bolt to tighten and loosen, vs two if you have to double nut them, and if your careful you can also put them in with an impact, and make things even faster, if you want. The only problem is it only works for installing them and not removing them, but that's what they make stud tools or double nutting for.
As far thread locker, personally I wouldn't do anything but oil them lightly. Being a stud, when you torque the nuts down on the heads, they aren't very likely to back out since. Usually the temps in and around the heads are high enough that any but the really good thread lockers aren't gonna hold very good anyway since most of them are designed to release with heat. Also if you do lock tite them in, and it does hold, and a few years down the road you need to do something that requires removing them, being where they are, it can be a real nightmare. This is my opinion based on experience, but, personally, if I wasn't 100% sure I'd still consult the mfg first since you can never tell what the engineer that designed it was thinking...I've seen some odd stuff out there recently...LOL Hope this helps.
