6.9 here, same 3/8 bolts though. I broke one when I took it to 85 like the book said. I replaced them all, put red lock-tight on them, and took them to 60. None broke. Does this help?

I am at 50lbs now, but i didnt use lock tight. i put boltprep thread sealant on them. looked like they had locktight on them once,some red residue. when i took this off the doner truck. it appeared to have never seize on them. still dont have the clutch on it yet. thinking about pulling them back out and cleaning it up and putting lock tight on it same as you. there should be a 'factory method' and torque spec for this. we cant be the only two on this forum with 3/8 flywheel bolts that has needed a clutch. need info fast want to put this in today!
