I had a Pertronix in my old Vette, it worked flawlessly, no issues ever.Where do they recommend drilling these holes and what size? While i was typing this I decided to call MSD...I'm on hold at the moment, #11 in Que...LOL
So here I am trying to seal any air entry point with Dielectric grease

They also recommend drilling two holes in the 6AL box if mounted upside down(which mine is). They say condensation will form and collect on the electrical board. They want these holes in the base(feet side)
