You're description is kind of confusing because you are referring to "front" and "side" of the engine incorrectly. If you mean the leak is coming from the same side of the motor as the exhaust manifold there I can't think of anything other than the freeze plug or maybe knock sensor. The common coolant leaks on these engines are LIM gasket, coolant elbows (usually not used with fiero swaps though), the little cover plate on the LIM below the throttle body, rear or front cover gasket and the usual places like waterpump and tstat housing.
This leak is definitely not a LIM leak so I would agree with some of your other possible causes. Its been too darn cold to get back into the garage of late but this weekend I will get the heater going and see what gives.
AFAIK, the front of the engine is the end with the water pump, the rear is the one with the trans on it. In transverse mounting. then I refer to the front side and rear side. How else would you describe it. The leak is on the front side
near the firewall. The top of the engine is completely dry. The leak is dripping along left to right on the manifold shield. Looks like its somewhere in the vicinity of the exhaust manifold bolts on the trans side. I am expecting that as soon as I pull the heat shield off we should see the leak. Thanks for the reply.
