Doug Thorley Headers with SB Trick Flow Heads

I have a brand new set to go on my Duster. Going to dyno engine with both these, and the Stahl headers it currently has.

Are those the 5302? I got ones like these...have to rebuild the #3 tube to clear my 65 steering box. Modded #5 to hug the block more to go behind the steering box. I got them for $25 as the bottoms of the passenger side collector is scraped flat and the pipes look like D's. But the collector comes off to reform the pipes, winner winner! IIRC Hookers are welded in Mexico..maybe they should be called 'Talonador'.
