I agree, It's risky to touch it.
Though, by the time that happens, things are pretty corroded and old in the
'head gaskets' department any way.
The one I did  responded to removing and resealing the one nut, but it IS
risky all right.

Subject: Re: Coolant leaking at upper head nut

Don't touch it for now, it may seal itself back. Coolant is corosive, with
time, it will built coat of dry coolant and seal itself, i know, i have seen
that lately in Mexico. If not, well, you have to seal it back. But it may
create damage ealsewhere. Those 8 nuts are fully needed, one loose and the
head may move. 50/50 chance i would say, who knows.

Good luck, Ben
