Those are leaking pretty heavily. Not sure a re-torque will fix it. I wonder if the head bolts are bottomed out and keeping the gaskets from sealing. I'd have to agree with an earlier post. Heads need to come off and see what the issue is.
Serious damage will occur if a cylinder fills with coolant and you try to start the engine. Broken pistons and bent rods. Not worth the risk in my opinion to just torque the head bolts again.
