.060 over motor stock heads barn find beauty. Has an Accel dual point model 30302 w/Champion J14Y plugs in it, car starts and runs daily, distributor cap is good, but rotor and points worn bad. (Going into winter storage) So I'm putting a Pertronix points eliminator module in it, w/Pertronix coil. Any Spark plug does and dont? I've read Champion J10Y may have been stock, but curious what not to use??? The J14Y are clean over all.
