Thanks guys, I appreciate it!
The dyno headers were made by REF. We called him up and asked if he could make a set because the FE headers that our local shop has don't have the EGT bungs, only have the O2, and they are smaller diameter. We also had kind of a crude setup for the run stand, those were Galaxie headers flipped upside down. These headers should work for both dyno and our run stand. They are 2" all the way, no step. They may not be optimal for all applications, but we needed a one-size-fits-all set.
The fuel tank is an Aeromotive deal. Ordered the tank complete. It works with carbs and EFI, just have to run the correct regulator at the front of the car. We haven't run it yet so I can't say how loud it is. In this case I wasn't worried about noise at all, but I thought the in-tank pump made packaging much nicer.
