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.
not sure on the valve size, but it is a clement head and barry young is working on it for me to get a little more, so a good head, 356 cam 35mm tillton carb 1.2 rockers, 88mm boreOpen 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.
