which header for JR supercharger setup on 1990 NA?

[desertfox]

i'm thinking of replacing the stock exhaust manifold with aftermarket headers in my car. i know that there have been a few threads about headers but i would greatly appreciate insight from owners with the Jackson Racing supercharger kit on a 1989-1992 NA who already have aftermarket headers installed in their car. which brand would work well with this setup? my car already has a Loch Stewart hi flo cat and a Loch Stewart 2.5\" exhaust. i'm after more low to mid-range grunt as the supercharger makes the car a bit sluggish under 2500rpm.

thanks for any advice you can give.
