AZC Oil Pan Drainback

Hi all, 

 

I recall reading years back that the AZC pan can have oil drainback issues if you're moving a lot of oil, and the fix would be drilling some holes in the tray. 

 

I currently have my AZC pan taken apart for another engine and figured this would be a good time to perform this modification. 

 

Does anyone know where these holes should be drilled, how many, and size? 

 

I was thinking something like the attached where the red dots are (excuse the mess)

Images in the thread above didn't work for me but what was discussed made sense. For reference I ended up drilling 4x 3/4" holes on the windage (passenger) side of the tray.
