Can 12v 80w headlight bulbs be safely used without damaging the harness or blowing fuses?

It's a risk.

80W (at 12V) = 6.7A rising to 8A at 14,5V for each bulb.

The battery is 12V, the alternator makes 14,5V to be able to charge, so when the engine is running the voltage is 14,5V.

Check fuses. If the fuses can take it, so can probably the wires. The fuse is supposed to be the weakest link.
