G'day all, I would suggest that you do not have to remove the head. I would drain the coolant (after marking the leaking studs of course). I would then in turn remove and replace each offending stud from the block using two thinner than normal 7/16 UNF nuts locked onto the stud. I would then use the permatex No 4 suggested by O D on the block end of the stud and re-insert the stud to the block with the two nuts on the stud. I would then unlock the two nuts and move onto the next offending stud. If you are not sure about the process, consult a mechanic on the matter. That is what I would do anyway. Good Luck Peter Toet
