spark plug gap

I was wondering what the proper spark plug gap is for my 400M.
It has a MSD 6A ignition on it with MSD blaster coil. Any info will be helpful.

I am running the same set up on my 400 except that I also have the MSD dizzy, I am running .60 on my set up, and it works fine

I e-mailed MSD with that very question and they replied with .050-.060". I'm running a 6T, blaster coil and MSD dist.
