Doug, I have never done it, but I would tap and plug them. Plenty of grease on the tap and the swarf should not be a problem. The threads do not need to be that deep, either, and some hi temp Loctite. I would be forever worrying if I had anything there not actually mechanically fixed.

Done heaps.
If the inlet manifolds are off, tap the heads, fit a grubscrew, done. Only tap down a few turns, just enough to bury the grub screw.
If the manifolds are still on, whatever fits in that hole, and rivets as described have been good, and the original clamp plates refitted to hold them in place, and to save shortening those 12 studs.
