Southie all cam followers are fine and in good condition damage is as above plus some light marking on some of the piston tops

Phunkynova, I read in a book on cosworth engines about the phenomenal strains put on camshafts at various points in the 4 stroke cycle. They are pretty much at their safe limit during hard revving. A sudden stop like a rod letting go would easily be enough to cause that failure.
That head needs welding as the damage is on the seats
Was it in 3 pieces when you installed it?
I think the engine is totally tattered.
If it was me I would be starting again with a new engine.

Graham, the head is saveable but will need a fair bit of inspection, the cam has broken due to the valve to piston contact, as I suspect also happened to your old cam.
When the head was originally done all the factors of the engine you had were installed in the head/ cambox mods, you will need a minimum of guide work, tosuit the new valves, seats recut and angled, piston cut outs.
The head will not need welding, if the damage is all in the pics posted.
What cam are you running,this worries me because I want to run a 285 cam in my C16SE build and I've been thinking I could have this problem????
I wouldn't be able to drive it again without wondering if something else inside the engine is going to let go and it would take away any enjoyment.
