Second, if you don't have one, get a Dremel, and make threadchasers for all the boltholes, in particular, Block(of course), Cylinder head holes for both the intake and exhaust manifold, even the top of the lower intake, they will be full of goop/metal and you don't want to break bolts. Before you install anything clean those holes and make sure they will accept a bolt. Fixing boltholes is a time consuming(waiting for the kits) job you may avoid. I used Brakekleen and a ton of Q Tips.

It's not uncommon for the manifold bolts to loosen up after time. They usually take out the gaskets and you'll hear/see/smell the leak.
As for the coolant leak, have you looked at your front cover gasket? They like to go and will leak coolant in the exact place yours is leaking coolant from.
A lot of head gaskets will have tabs which will stick out when installed properly, the gasket may have torn during head removal. Your engine doesn't look like it's had a head gasket leak, especially into any of the cylinders. Coolant in the cylinder would make it nice and shiny in there. That usually happens with a cracked block as well. Oil/water mix is another tell tale sign of a cracked block, or combustion gasses in the coolant.

Thanks, I did the front cover already. If you look earlier in the thread, you can see water coming from the head. It came off clean, so it was obvious that the gasket was torn. Someone did this job poorly not too long ago.
The boltholes in the aluminum engine parts, especially 8mmx1.25 and smaller are really brittle. I have threads that pulled out very easily. It could be from my own rough treatment, but I can promise you that I will avoid torqueing a bolt down without at least a bit of grease on it from here on out. I also now have thread chasers for most of the sizes. Putting in timeserts or heli coils is not especially difficult, but I would rather not spend the time or $80 per stripped bolthole.
It’s a $&@&in’ drag. I timeserted two of my upper manifold bolts so I don’t ever have to eff around again.
I am noticing this time around a bit of Vaseline or grease is a really good idea. Of course, the larger diameter holes seem much tougher. The

Making some progress. The heads are back on. Everything went smoothly until the valve covers.
It it was getting late, and there is one screw on each cover that won’t drop in. I ran a small screwdriver down the hole, and it is lined up. I just couldn’t get the screw to drop in.
I plan to work on it today between college football games.

And of coarse, I dropped one of the upper coil mount screws. The upper intake was partially on, so hopefully it didn't make it into the engine.
I've pulled the upper intake and coil looking for it, no luck. It looks like it would fall on the valley pan gasket or transmission, but I've yet to find it. Came inside to cool off before I go at it again.
