A friend, who sold his early Bird. gave me a bunch of different spark plugs.  All Autolite  46, ASF42C and BF82.  I usually use the 46's, but are the others a good plug for a basically stock 312 in a 56  TBird and a warmed over 312 in my 54 Ford.    The Bird has a Pertronix II, the 54 a stock points dizzy.

Thanks for any info.
