Schumacher tri-y headers

I know they're out of stock, but I'm building a 451 at work for a customer who needs power steering.
Do the Schumacher headers work with the low deck in a 71 dart with power steering?
He also doesn't want to run a fender well header.

So if anyone has any experience, or other options I'm not thinking of please let me know.
Thank you
I have a 1968 Barracuda fastback powered by a 400 based 512 stroker, backed by a 4 speed. I run Schumacher headers with modified 3 inch collectors that go into 3 inch exhaust with an H pipe and 3 inch Magnaflow mufflers with an 18 inch case. I have manual disk brakes with power steering. The fit is great.
