Exhaust Gasket leak and stud broke

[cashville]

Ok, I was able to take the broken bolt out with a pair of vise grips.
After that I put the new studs, and I re-used the same gasket because the only ones I could find for sale that would ship to my country were Felpro, and I heard a lot of mixed feedback, so I just re-used the gaskets.

I tightened all the bolts a first pass to 11lbs, and a second to 18lbs, like in the manual.

I noticed that where the broken bolt was, with the new bolt tightened to 18lbs, the header was still not even making contact with the manifold, so I had to tighten it really hard to get it to make contact. (It probably stayed a lot of time with the bolt broken, so it got bent out of shape)
Then, I connected the spark plug wires, and turned on the engine, but the noise is still there, A LOT more quieter now, but it's still leaking air, I can hear it.

Now, I don't know what I should do, if I should tighten all the bolts a little bit more, especially the one where the broken one was, or maybe it can be a leak from the gasket, although I don't think so.


What do you think, should I tighten the bolts a little bit more tomorrow?
