Hedman Husslers..lots of dough though..."angle wing" style. I got a pair of antique Cyclones that are the same. HEdman offers a few sizes/port patterns too, important for a W2 or big stroker. Spitfires will be your cheapest option unless you want to mod some block huggers, direct #1 tube into #3 tube at turn back and then fill #1 spot at collector. There was a post for sale that had some good pics. Props to the original mod'r!
