I have a 1967 289 coupe.  The previous owner put in Autolite 45 spark plugs with gaps over .040.  I recently converted the points to a pertronix 1 with flamethrower 10,000 volt coil.  I did not change the spark plugs, and the car runs well, although with a slight tick.  I want to put in fresh Autolite 45s and the book calls for gaps between .032 and .036.  Should I set them to the same gaps as the old ones or set them lower so they fall within the listed range?
