I would usually use blue Loctite on flywheel bolts but I have some new ARP bolts and they came with this new (to me) special ARP lube which they recommend. I'm just uneasy about using it on flywheel bolts, shouldn't I be better with Loctite on those?
ive not used ARP flywheel bolts before !
ARP offer special lub for its bolts / nuts on studs etc to achieve the correct torque with a torque wrench for things like engine head & bottom end studs nuts & bolts, which require a more critical torque value & no lub metal to metal tightening friction will alter the torque readings .
IMO for a fly wheel / flexplate / torque converter bolts install them dry & ALWAYS use Loctite on threads & use factory torque specks !
think of it as kind of a reverse of don't use locktite on mains & rod bearing bolts / nuts
That is kind of my thinking exactly tan top. Not being an engineer, I had to wonder though. As a sidenote, I also picked up some ARP pressure plate bolts and the special lube was not included. It's another area where I have always used a thread locker and will again.

I know I've
always used locktite on pressure plate bolts. Flywheel bolts on the other hand I
think I also used locktite but not on every install. I've been using the ARP flywheel bolts also, but saved the special lubricant for elsewhere on the engine
I just did a new clutch and flywheel the other day. I used Grade 8 bolts for the flywheel and the Mcleod pressure plate bolts supplied. Used blue Loctite on both and torqued to factory spec.
And a call to ARP revealed that they specify their lubricant under the head of the bolt and thread locker on the threads.
