Jack, Depending on how much of an engine you are going to build, would depend on whether you need big tubes or if a standard 1&5/8 tube would be fine. Here is what I have found for both on a wide body Javelin. For 1 & 5/8" tubes, Headman fit great and are reasonably priced. If you need a larger tube, 1 & 7/8 Hooker Super Comps also fit nicely. They are a bit more expensive but they are worth it. Which ever way you go, make sure you get them for a Javelin and they should fit just fine. I would stay away from Black Jack or Cyclone. I have had them in the past and the fit and seal for crap.
