Pretty sure it's m7 on the valve cover threads. Will need to double check. I did it about 5 years ago.

I've used helicoil on threads for the valve cover (2 of them in the past) and it's still holding fine. On the ofh I've used ez lok on the thread which has a dowel sleeve (this works best as you can still use the dowel sleeve with this method). For the others without dowel sleeve use helicoil.
