In my restoration I have "found" so many bolt threads that are fine threads where in normal engines of today they are coarse threads. I too found this out the hard way when I tried to "clean up" so threads in the block mounting holes for the motor mount plates. Its like measure twice... Cut once...

Take extra time to make sure it is all correct bolts, double check everything, and ... - I had to basically throw away what should have been a beautiful flywheel, clutch disk, and pressure plate that probably only had 10 to 15 minutes of driving on them because somehow junk hardware store bolts of wrong size got installed - unbelievable the damage to each in such a short period of time and just lucky that was extend of it :)

Or as a friend said: Tighten bolt until it strips, then back off a quarter turn.

Good point Mike.

The bitterness of poor quality remains long after the sweetness of low price is forgotten.

If you eliminate lock washers for Loctite products you may end up with bolts that are too long and bottom out or interfere with something else. If you want to use Loctite go ahead. but use lock washers too if called for.

Mark, you will not find any torque specs for anything in the technical bulletins. Torque wrenches were not available until WWII
The book calls for lock washers , use new ones.

I believe the torque for flywheel bolts should be 60 ft lbs, but I'm not sure. Also, the parts book calls for lock washers, but thread locker might be a better idea for this. Looking for other people's experience
