Cross section of a cracked cylinder head!!

[s car go]

Many of you have replaced your cylinder heads,as a result of cracking,but did you ever wonder just where that crack ended up??
What we need is some idiot to cut a cylinder head in half!! Here you go:-

First image shows the cylinder head cut through,and the second, the crack between the valves extending up to the water gallery!!
