At what point will a -6an Head Vent become Insufficient?
use an SAE thread not metric... and choose your tap/drill size based on what mcmaster has socket head cap screws that are pre-drilled for safety-wiring. You'll save yourself soo much of a headache! my 2 cents.
(reason why sae... mcmaster only sells pre-drilled SHCS's in SAE)

I've been an aircraft mechanic for 14 years and have safety wired 1000's of fasteners. With that said, I can't ever recall seeing a DIY auto mechanic performing a safety that was anywhere near correct. For that reason, I recommend M5x.8 (14MM long) hardware with lock washers and red loctite. I'm using that stuff in my car because I don't feel like bringing my safety wire pliers home from work, and I have complete trust in the aforementioned setup.

Eric, do you remember which ones you went with?

Edit: For some reason the link won't bring you directly to the SHCS page. Thus, I'm just wondering on what length/size you ended up going with.

Either 14MM or 16MM length is fine, depending on how deep you drill it.
Personally, I drilled the holes a little deeper than 1/2" and went with 14MM hardware. Considering the thickness of the lock washers that I'm using, and the thickness of the baffle itself, I'll have roughly 1/2" engagement of threads, backed up with red locktite and lockwashers. I'm comfortable with that.

The dip stick tube sits above oil level so you should not have much of a problem. Yes we use the inspection hole on the front of the bock. Here is a link to the fitting we use.
