Factory about 35. I usually go about 45, but no more than 60. Most hot rodders run as wide a gap as they can get away with & even index sometimes. Usually when you buy, the gap is about dead on to specs. measure a new one. If they are the washer type, you will feel it compress when you tighten-don't over do it.
