I did the same conversion as reno4u2, replacing the outer low/high beams with Hellas, retaining the stock high beams and wiring it all with relays as per Daniel Stern's instructions.
It makes a big difference, especially if you use heavier gauge wiring, which I highly recommend. I used some 14 gauge wire from a big box hardware store.
One thing to note: if you use relays, the bulb out indicator on the dash will light up, because it doesn't "see" the proper resistance in the switch circuit. I found there's a way to make that functional using a pair of 4 Ohm resistors in the switch circuit to make it think there's bulbs there.
