Spark plugs?

[Lew]

I just got done with upgrading an old points setup.  Went with a Rivera advance unit, Blue streak points and condenser, a 5 ohm Dyna coil, a set of Accell 8.8mm solid core wires and Autolite 216 non-resistor plugs.  Wow, what a difference new/quality parts make! All this got me to thinking about spark plugs.  I realize there are several choices of heat ranges and brands that are preferred over others.  Curious to know what spark plugs you guys are running and why.

         In My '73, I Use "Champion J12YC"
  Why? I Don't Know. They Seem To Work Well,
And, Don't Foul As Often As Others I Have Used!!!!
