Nowadays, I have little reason to remove the OHV covers on my 2001. The valve lash just doesn't require adjustment that often...maybe annually. Well, if reasonable care is used, you'll never experience damaged OHV cover threads. But, one episode with a mechanic with poor skills or little experience and....well, its Helicoil time as you point out.
It is unlikely you'll ever have problems with these threads again (leave the torque wrench in the toolbox).
Wish you had photos.
