I have seen coolant leakage at some head nuts many times. These slides show what I have done to fix the leaks.

Bob B,
I didn't know that head studs were to be installed HAND TIGHT. Thanks for that important info.

I coat the threads of the studs going into the block with Indian Head shellac.
While still wet I adjust the depth of the studs into the block so the tops of the studs will show the same amount of threads above the head stud nuts.
Allowing it to dry and set before installing the head will generally keep the studs from turning when the head is installed.
Just makes for a nicer looking job when done.
