Default 1936 Spark Plugs

I am working to restore a 36 Club Cabriolet for judging. I am building an engine (36 LB Block) with NOS aluminum heads and according to the 35-36 Ford Book the correct spark plug is a Champion 7. I was able to find a NOS set of Champion C-7's with the brass hats and screw on tops for the hook type spark plug wires. My question is what is the difference between the C-7 and the 7 spark plug. Also, for those of you who have attended shows with your cars, do you run a different spark plug and then switch to the "show" spark plug. If you do, what spark plug do you run for "fun"?
