Forza Head Case 1964 Ferrari Cylinder Head Combustion Chamber Restoration.
This is a photo of a Forza Head Case 1964 Ferrari Cylinder Head. The arrows in this Forza Head Case Photo point to the 45 degree valve seat. These seats have been cut too far into the copper alloy valve seat inserts. The term used to describe this is, “the seats are sunk”.
Any valve job removes material from the valve seat inserts. As the 45 degree valve seat is cut it becomes wider and lower in the cylinder head. A valve seat that is too wide requires a top cut. Most Valve Seat Inserts need Replacement when the top cut has to remove material from the combustion chamber.
