Yup,
Holes could have been elongated.
Also the surface on both the crank & flywheel needs to be perfectly flat.
If gouged up, the flywheel will work it's self loose again.
And........
ARP makes great bolts for the flywheel.
I think Aaron at driftmotion has them for $21 (for 6)
They come from ARP in packs of 8 (for more $$).
ARP p/n 203-2802
When you used the thread locker, did you clean the holes with a good solvent first?
Also, if you do have a damaged surface on either the crank or flywheel,
and it is just a little,
you can pick up a hand stone from any machine shop supply.
The medium indian stone, 1/2" square x 4" long works the best.
They are perfectly flat, and if used with some light oil,
will take off the high spots, but not anything else.
This will give you a good flat surface for the flywheel to sit against.
Do both the crank & flywheel.
Torque the ARPs to 85 ft/lbs with locTite.
