Rebuilt C7ZE 289 hipo heads with thermactor ports with a 6M22 date code.
Asking $3000 for set.
These heads were rebuilt in the late 1980s and have been on the shelf since, never run, Then are complete except no rocker arms. Original ford screw in studs, springs and retainers.
All new Sealed power valves from the 1980s, so most likely they were made in the USA back then.
The heads have gaskets on them because they were sitting on a rebuilt hipo that was on a stand in our workshop.
They have never been run after rebuild
