That looks like it didn't have enough pressure on the head gasket between any of the cylinders. If you look closely can you see the block and head machining marks pressed into the gasket all over or are there smooth areas?. Does the LR manual require a head re-torque after a few hundred miles? Its critcal on the Perkins engines. You will see elsewhere I had a simalar problem - head gasket fail, then change, then 6 months then fail again. It looked very much like yours, I found the block was burned where the head gasket had failed (it failed the same place twice) and ended up changing the block as I felt sure it would fail the same place again.
