I'm not even sure at how much torque the last bolt is, because it's the only bolt with bad access, and my torque wrench wouldn't fit in that place. After the others I could get a feeling of the 18lbs, and put it around that, and I did but it was not enough to close the gap. After that I tightened it a lot, because a lot was needed for the header to go back into place with no gaps.

What I'm thinking of doing tomorrow, is do a leak test and spray some wd40 around the manifold (will start with the place where the broken bolt was), and see if I get a different engine idle, just to detect the leak and make sure it's really coming from that place.
