Many people do not have the correct frame pads and since most headers were made off a real big block car with the correct big block frame mounts they don't fit with the engine centered in the chassis like a small block.
This happens with most headers, other than the few like Lemons who actually make headers specifically for a big block in the small block location. Here's a pic and some more info:

Not necessarily true. I have NOS big block frame stands for my 69 that shift the engine to the passenger side properly and I still had to dimple my Hedmans and would've had to dimple a set of Hookers to fit near the steering box. If the #5 header tube does not loop over the #7 tube, then the #5 tube and possibly #7 tube are probably going to hit a power steering gear box no matter how correct the frame stands are. I've seen people place shims under the drivers side frame stands to create extra clearance. Some power steering boxes stick out more than others also. I had to rework my #7 tube when I changed to a different ps box.
Additionally, he said the headers are hitting his idler arm also, so shifting the engine more to the passenger side would make this worse. I saw a thread where a guy had the same problem with his Lemons and had to send that side back to get reworked slightly.
It's a difficult fit for any header manufacturer and it's a crappy situation for the original poster because of how pricey the stainless headers are and how pricey it is to return them to have them corrected.
