TTI 340 headers install

Hello everyone, I’m getting ready to install tti 340 long tube headers in my 73 Duster. While the engine is out I’m considering power steering. So my question is does anyone have a 73 duster with a 360 and factory power steering with these headers installed. And if so did you have any problems with this installation. And do you have any advice on this matter. Thanks for all the help
