Headers for a small block dart with power steering?

Dougs D453 on my 70 Dart
1/2 inch higher with washers, drivers side motor mount
No washers passenger side stock /6 torsion bar very close to tube , my new 1.03 torsion bars will not fit without dinging a tube
Still, coupler and tubes very close to ps box would need a heat shield and or a cooler

Just bought an aftermarket manual box 16.1 ratio, stainless coupler on order

It appears that the same headers on A bodies have different fitment, due to the lack of quality control on construction, which makes up to 1/2 inch difference, which can be significant

This will be my last complete build, I want to drive it and not need to frig with it !!
