what would be the best header for an open 390 on a kart for small tracks, I know there are not a lot of headers like there are for clones.

Open as in how "open?"
What size carb, cam, ratio rockers, what size valves?
You don't just pick a pipe out of an online catalog without considering the rest of your build. These parts all have to work together.
We have pipes built just for our 390 opens...they may or may not work for your build.
