Too much voltage to headlights?

I got my charging system under control by replacing the field wires. I ran 14 gauge wire from the alternator to the regulator. With a relay powering the circuit. 13.8 volts at idle with no load, 13 volts with full load(all lights and the blower motor running on high). 14.2 volt at cruising speed. I also have a 4 gauge wire for the charge wire going straight to the battery(with a 100 amp circuit breaker).
