Why Modify Cylinder Heads?
If the performance, economy and reliability offered by modern engine designs could be achieved within the engine of your classic vehicle, would you be interested? The truth is, a lot of what makes a modern engine perform lies directly in its cylinder head and while it may not be possible to exactly mimic the performance that modern cylinder heads deliver, narrowing the gap between new and old engine technology is still very possible.
