Hi, it's a real good thing that you brother is a machinist. The adapter is top notch work. However that was good for you current application. Why not go ported injection, with the help of these. Your brother could help you go duals or mod a IDF stlyled intake manifold already in the market, by adding these injector bosses; you would have a real nice fuel system. These injector bungs are right up your alley, they come in steel or Aluminum. There prices are not bad either.
As always good luck
