re vamp

Here's the poop:
My car is a '65 Dart
Installing a set of Indy 360-1 heads (245 series), in lieu of my W's, with matching heddman man hustlers. I'm looking for a set of 2"X3.5" hedders that will fit these things.
Or do I modify the Hustlers somehow. The middle exhust appears to overlap the two inner exhaust ports (if you can believe the gasgets). Thanks.
