Absolutely 10 are bad and kept pulling at about 30 ft lbs and never made it close to 60 which I image is on them at operating temperature with motor expansion.
When case threads were chased (do not recut) this can remove more thread material than we think. I'm finding out more..
A little wobble of the stud is fine when assembling but excessive wobble is not. If you use Loctite the cylinders heads and cam boxes must be torqued down quickly before it sets or it sets with Loctite on the leading edges of the case threads which will collapse under loads
We need to be very careful when cleaning out the threaded blind stud holes of our cases!! A little to aggressive and you'll be pulling your engine apart in 1000 miles.
Sorry to those this subject bores.
If you want this moved go for it.. I wanted to do my part and have.
ARP will likely revise their torque recommendation bc 38 is way wrong. Torque is torque.
I said all I need to say here. Have a great weekend it's driving season again!!
