Question '98 heads on a '99 LS1

So I've got a pair of TEA Stage II heads from a '98 F-Body that will be going on my '99 Z28 soon. I also bought a couple used perimeter bolt valve covers since the center bolt versions won't work. I still have to find a set of '98 coil pack brackets. I was wondering if there is anything else I need. That is, my '99 coil packs will work fine, correct? Do I need a '98 wire harness? Or, do I modify the '99 wiring? Do I even have to do anything about the wiring at all? Am I missing anything else? Any help is appreciated.

98's do not use a bracket. They bolt directly to the valve cover. I dont see why your wiring wouldnt work.

The wiring harnesses are different, but only because the wires are more organized for the 99+'s, you should be able to make what you have work using the 98 valve covers, and your stock coils/harnesses. As 98camarod said, the coils just bolt directly to the covers. Don't put the last bolt on the bottom in on the #8 coil pack in, you'll never get that hoe out.
