are these proteas dead and if so should I cut off the heads? Regards Bob

They aren't dead, but they do seem to be disturbed. This seems to happen in compacted soils, soils that remain too wet, or otherwise too dense.
I would cut any affected blooms, leaving the others. Treat with a mild fungicide, and do your best to ensure that it doesn't remain too wet for too long. (If possible.)
