318 Spark Plug Gap?

My Champeen coppers have been in there since 1999, sparked by a Big yellow SuperCoil.
I was gonna change them in 2004 the last time the engine was freshened, but they looked so good, I left them in there. The new replacements I bought are still in the trunk. The car went 93 in the Eighth on those ancient plugs, in summer of 2004. Cheapest plugs I ever bought. I haven't even looked at them since 2004.
Your results may vary,lol.
