I am trying to help someone put back together a 426. It looks to me a retainer came loose, lost the valve down the hole then the piston tried to beat the poor valve back into it's rightful home. The head looks like it was used as a test piece for new industrial air chisels! Anyway cost is pretty steep on a new OE head, anyone with bright ideas on a repair shop? Thanks for the help.
