Had some free time so I started working on my exhaust. After adjusting the valves last week, I was still hearing a ticking noise and read somewhere the 2nd most likely cause would be an exhaust leak. There appeared to be a little scorching on the cyl 3 gasket so I decided to look into it. Planning to replace gaskets and studs, resurface the manifolds, and repair a hairline crack on one of the pipes to the driver side turbo. Removed both manifolds without a single broken bolt. Gaskets were in pretty poor shape on the drivers side. The passenger side gaskets were in much better condition except for the scorching on cyl 3. It also looked like that gasket had been installed incorrectly, cutting off some of the airflow.

I'm going to try high-temp JB weld on the crack and hope for the best. I'm open to suggestions if there's a better solution.

The gaskets only fit one way. The EGR port below the large opening is not used on the Delorean. The hole just remains blocked off by the manifold flange.
Is the cracked pipe a casting or bent tube?

Cool. Yeah, when I did mine, 3 of the 6 gaskets were leaking. At least 2 of the gaskets were installed backwards (see picture). I can't imagine anyone not paying enough attention to do this.... Well, maybe I can.
When I was done with the work you are doing my ticking sound was gone and there was a noticeable improvement in power and quietness.
One tip, I suggest you apply high temp gasket maker to both sides of the gaskets like so:

On 2nd look, the gasket wasn't backwards, rather the corner was torn like yours so the gasket was off-center. I didn't take pics of those b/c they were otherwise unremarkable.
My car's PO cut the mufflers off so it's always been really loud. I added cats in October that took the edge off the noise, but it was still pretty loud. The manifolds and turbos are in good shape, but I really need to replace the pipes that join the turbos to the manifolds. (To answer someone else's question the crack I need to patch is in the pipe on one of these.) Turns out those aren't so easy to come by You could see it needed gaskets but I kept putting the job off b/c I read so many stories about breaking studs. Luckily they ended up not being an issue. Other than the ticking, it'll be an added bonus if this job quiets it down a bit.
I read on the permatex site as well as a few other places that gasket maker isn't really recommended for use with a gasket as it spreads so thin that it's not effective under high heat/stress. Instead they recommended a sealant, but even then I read several arguments for just using the gasket alone, but I haven't decided what I'm going to do yet. That said, the side that had permatex on the previous gaskets didn't look like there was much of it left.
For the crack, I would find a good welder to see if he can repair it rather than doing JB Weld. I had good luck repairing a crack in an exhaust manifold from a Porsche. Definitely the $40 weld was less expensive than a new manifold.
