Rainmaker:
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

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

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.
