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?

[dreracecar]

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.
