Anyone who knows anything about lighting will tell you not to put hid bulbs in a reflector housing. When I bought my 80 the previous owner had installed a cheap hid kid, just the bulbs and ballasts into the factory houisngs. Shortly after owning it one ballast went out so I swapped regular halogens back in. The difference in drivability wasn't huge but it cut down on glare a lot.
I've since done a d2s bixenon retrofit into depo's and they're amazing, it's like driving with suns attached to the bumper. I'd seriously consider saving up to do it right, that and it will give you 4x high beams so aux lights are no longer necessary.. the savings there may factor in.
Whatever you do, upgrade your factory headlight harness to the one Slee sells. It's a common weak link with the 80's, the resistance in the factory harness is too high and chokes performance while posing a potential hazard if you increase current draw with higher output bulbs.
