Here is a pic of the header I chose for the thick, machinable, mating surface. Around $100 on the ebay, probably Asian, had the name of MANZO. I does best with longer manifold studs than the OEM.
This looks almost identical to the one I got. I got OEM studs because I love throwing money away. I did have to get OEM gasket. The ebay one did not fit properly.
I still still have the OEM header. In the original operation, I couldn't get a CO2 sensor out, so I put a replacement header on. Since then I got the CO2 sensor out but stripped out the bung.
I can't find anyone to repair this as yet. The idea was to gut it and keep it for when the ebay header fails and return to stock.

Ooof. I am hoping my ebay header doesn't fail. I don't see why it would? I mean, it's just a piece of metal tubing. I am more worried about the gasket leaking/failing. But I guess to be safe, I will keep my OEM header. I was hoping to sell it though 🙁
Thanks for jumping in, SW-I!
