TR6 Spark plug gap

I read somewhere that if you have electronic ignition/super coil that the spark plug gap should be .030-.035. Is this correct?
 
I have the pertronix and have my gap set at .030
 
Hey again...
It's more the type of coil that allows wider gaps...But when I had a Pertronix Ignitor and a standard coil in my 74, I had no misfires with my Champion RN12YC spark plugs gapped at .035.
I'm back to points now with a Bosch Blue coil and when I was using the RN12YC I had no misfires with a .032 gap.
If you start getting misfires at high rpms, it could be because you have too large a gap for the spark to arc.
 
I tried 9's but I found them a little cold and tended to foul, especially if there was much prolonged idling.
At sustained high speed, they were OK...12's won't foul even if you find you're burning a little oil.
