Pertronix ignition plug gap

Hello Folks I have a 68 404.1 with a Pertronix ignition upgrade, it has everything including rotor, distributor cap and wires, it also has a flame thrower ignition coil. I have looked online and in all the documentation that came with my truck and cannot find what the proper spark plug gap should be for this setup, its got to be MORE than the original military equipment, that was like 1/2 a MM, if anybody knows the correct gap for my application I would sure appreciate your input please!
Thanks

Pertronix dont make a difference, 1/2 mm is ok if the compression is 7:1 , standard for the original engine...

corrected post - thanks Phil - I will be filling my gap between my ears with coffee now - and good morning to you Sir. (oops)

Dave, you need more coffee. Reread his post. Oh, and good morning to you sir!
