I would try to figure out where you are leaking coolant first. Hose? Thermostat?waterpum?
Pretty sure it's not leaking in the engine - no symptoms relating to head gasket. Probably a small crack in one of the plastic components, I'll have it pressure tested next week.

What about the exterior bolts (not under valve cover)? Not a good idea to replace these? There's no gasket under those.
