took the head off

I took the head off of my 95 t-bird 3.8 and it looks like the piston is hitting the exhaust valve, what could be doing this ? strandid.... :banghead: :banghead: :banghead: :banghead: :banghead: :banghead: :banghead: :banghead:

Broken valve spring or retainers. You will have to replace the valve at least since it will be bent.
