Who do you recommend for preformed brake lines 69 Cutlass with disc brakes and aftermarket proportioning valve, no stainless?

I'd go stainless, though. They're not much more, look nicer, and last forever. The only downside is that they are difficult to seat the flares.
Expect to modify if you moved the distribution block for headers.

 

In-line tubing, another option
