I'm wanting to ditch my OLD low hanging headers, are these manifolds worth it?

The only problem w the hedman shorties, and I have a set that i test fit, but did not install is making the pipes fit around the steering linkage. TXstang84 has a 72 scamper with a magnum teener in it. He is running them. Pipes on it are a little creative to get around the steering. With the hi po ones you can buy head pipes from TTI that are direct bolt up. No muffler shop required. The way I see it, either way, your gonna pay.
