Yes!

But this is like a 15 minute job, it's not like debris will be flying around. Using oil will also help to contain the swarf.

@ abscate which cam cover hole is it?

I think front row , just under the number 2 coil plug.

Front row of the coil bolts, not the edge bolts

Tap threads
Clearance cam cover for M8 through bolt
Yup, on both. I'll pull a bolt out of Old Blue, too.
In DC, back in DE in the AM.
If you already own a regular M8 tap, investing in a bottom tap to follow up would make a better job of it.
An Ancient Machinist, he of the boring matter above, taught me the trick of laying a little bit of grease in the flutes to help catch the spooge as well.

From the parting line of the cam cover surface to the bottom of several blind holes I got ca. 22.97mm
The cover itself at the bolt hole pad seems to be ca. 20.30, but I had a hard time getting a good read due to circumstances beyond my control ( the head is in an awkward spot, it was raining a Deluge, and I didn't feel like emptying the back of the car.)
