Most commercial offerings go 45* 90* 180* bends,  having  custom bends will get pricey due to set-up charges.  Go with  6" radius bends cut in half to get length out of the port instead of a tighter bend and a straight off the port. Exit angle will parallel the flange angle and only 4  180* bends are needed and you can fudge the cut at the flange to get them standing straighter if you want

If you can get Ted to bend you a set he has no problem with custom bend. I use to get 3 different angle per set and cost was very reasonable.

I've gone to making my headers out of stainless. Way better, less hassles with rust and fatigue. You can get mandrel U-bends of every flavor from Woolf Aircraft in Romulus MI.

I've been told Stainless headers crack up? Is that an urban myth?

only because people tend to make SS headers thinner and that makes the service life is shorter,  You make them the same gage as mild and they weigh a ton.   So you wind up spending twice the amount for SS and can get 1/2 the service life

You might look at Shoenfeld Headers (? ) web site - lots of oval track headers and parts.  I have used them for plates and u bends.

  Buick 350 header flange is not super common as a SBC/BBC would be.  Lots of tube bends out there from varius supliers

When I did the set for my altered I made sure there was back shielding gas on the inside of the header pipe. I use a mini-Nerf football to hold the purge gas line inside the header pipe as I'm TIG welding the outside. I race pretty much every weekend during our season and after 19 years of use no problems so far.

The specific gravity for stainless steel is around 8000 kg/cu m vs about 7700 kg/cu m for mild steel so, yes they will be about 4% heavier than a mild steel set. But since you don't have to coat/paint them I'm calling it a wash.
