Thanks Paul for replying my post, do you remember which stud was it that was broken. Without the one in the lower middle might be able to hold better. I have searched that achieve, it appears that it is possible to replace the broken stud, but a very tough job. Not sure I can handle it. It would be nice if someone have can share their experience in replacing broken stud.

I have seen a head held on with 7 studs, but who knows how long it
ran before it broke again. (It was broken again when I got the van).

The guy had tapped the stud hole in the head and filled it with a
bolt (and sealant) to keep fluids from coming though.

You could try this, but I doubt it's a good solution.

You may in in a pickle my friend. :(
