Can't see your pics- - - - -the computers at work have too many firewalls and filters. If you've got flat washers or something similar between the bolts and the flywheel, that's probably the problem. Even lockwashers can cause trouble, unless they're the really thin star-shaped ones. Try installing the bolts without any washers at all, and using some high-strength LocTite on the threads instead of a mechanical locking method. Most flywheel bolts have an oversized head to assure plenty of contact area between the bolt and the flywheel, and they're also much thinner top to bottom than a regular bolt head. Torque the bolts so they all carry the same amount of load. I don't have torque values handy for that engine, but someone should be able to give you a ballpark figure.
