Best fitting headers for 70 Dart???

I’m getting ready to buy a set of headers and have read a bunch of reviews. There seems to be fittment issues with all of them. Has anyone bought a set that doesn’t require lots of frigging?
70 Dart originally a slant 6 now a 360 magnum with aftermarket mounts.
Power steering manual disc brakes
904 tranny stock suspension
A recommendation would be greatly appreciated. I know that some of the
Expensive headers fit well but I’m on an extremely tight budget.
