Coolant Leak, but Where the Heck From?

Engine is out, but dry on top 
With the amount of coolant leaking, you would expect a puddle on top of the engine that would then "flow" to the underside... but no such thing.
Looks like it's leaking from the cylinder block, where the drops are on the pictures. Either gasket or cracked/porous block. If cylinders come off, I guess it would need new rings (might as well), and then on both sides... So how much for those 3.8/3.9 pistons and liners
Could be this:
Good news, clutch is good, might need a bearing. Also, one clutch fork needle bearing was missing, so that was a good catch. Going to install the 997 tranny mount and possibly Wevo engine mounts.
Bad news, the cup upper control arms (doggies) are gone and replaced by stock rubberized ones
Now, about the gearing...
