When I installed my flywheel, I used Ford flywheel bolts. They are "place bolts" and apparenlty the strongest bolt available according to page 92 of Carroll Smith's "Nuts, Bolts, Fasteners and Plumbing Handbook". I'm not sure if it's still accurate, but he lists the P/N as B8AZ-6379A.

It's been a while, but I think mine came with some blue-thread-locker painted on the threads.

On Loc-tite, the red is for large bolts, blue is for small fasteners...such as 6-32 machine screws...i.e. very small, so if you want to use Loc-tite, use the Red. And by the way, I suspect the torque needed to overcome red loc-tite is insignificant compared to the 100 ft-lbs or so (sorry, can't remember the exact spec) needed to loosen flywheel bolts.

I do believe a properly torqued bolt doesn't need loc-tite. For example, I've never heard of anyone using it on connecting rod bolts.

But for piece of mind, I do use it....on the camshaft sprocket bolt and if my bolts didn't already have some sort of thread locker, the flywheel bolts. I did use it on the pressure plate bolts as well. Just an extra precaution, but probably overkill.
