In search of stock oem headers for 16v 4-age ae86 willing to pick up or have it shipped out of state?

I was in the same boat as you are now for a quiet some time. I ended up sourcing one from out of country on the site I have linked here. It took a while before a descent one popped up that had the Manifold and the lower collector pipe together, but I eventually got a descent one. Keep looking locally, but check that site periodically and you may get lucky. Good luck with your search.
