APE offers damaged combustion chamber repair. This is a good way to save those high dollar race heads that may have dropped a valve, etc. 

We completely weld up the chamber, them CNC a new combusition chamber.  Damages seats are replaced with APE bronze seats.  valve job is completed and head will be ready to shim and install. 

Please note that this is a little pricy, and if your head is stock, it is probably cheaper and faster to find a used one.
