I have a new set of round port headers. A guy I know bought them for a 69 GTO and didn’t realize there was a difference in d port and round port heads. It had been a while since he bought them and he couldn’t return them. I think they are stainless steel. Very nice looking headers. I will get pictures for you tomorrow. I will take $450 plus the shipping.

Pictures. The last one is shown next to a Hooker Super Comp that was on a 69 GTO. Fit looks similar. A guy I know bought these for a 69 GTO that had a D port motor in it. He didn’t know there was a difference in round port heads. I took them in on a debt. I am in a Christmas mood. Give me $250 and pay the shipping. Also includes gaskets. Let me know if you can use these.
