Why Is This Ferrari Head So Worn Out?

Today we're tearing down a legendary Ferrari 465GT cylinder head and taking a closer look at the engineering that makes these exotic engines so unique.

Along the way we'll examine the valve train design, combustion chamber, ports, valve guides, seats, and some of the unique features Ferrari incorporated into this V12 platform.
