Dodge 360 Water Leak

I have a rebuilt 360 I have dropped into a 73 Charger SE. I am having an issue with a water leak. On the right (passenger side) front exhaust stud, apparently there is a water port. I keep having a leak. I was told to replace the stud, which I did. Was told to put teflon tape on it to stop leak. I did, but it didn't stop the leak. I was then told to put high temp silicone on it. I did this too but still have a leak.

Any suggestions?
