Water leaking from head

[climberman]

I have about 49 miles on this 283 it sat for about 3 to 4 years before I ran it. Yesterday water was dripping from it after I pulled in the garage after shut it off. But from the back of the motor. Today I took a closer look and it is coming from the back of the heads. I could be wrong because it is so slow but I can't see anywhere else it could be from. And on both sides one side more then the other. I am hoping I just need to check the torque and tighten the head bolts.
