Summary of Uses
The reverse flow head was ideally suited to a production carbureted engine due to its low rpm performance and ease of manufacture. The design could be modified for high performance by porting (in particular siamese) and isolating the inlet manifold from the exhaust header. The configuration is also perfect for carbureted non-intercooled turbo-charging. However, the advent of fuel injection and electronic ignition has made most of the reverse-flow head's advantages redundant in a modern engine and as a result the design has lost its popularity. The reverse-flow head still enjoys immense popularity among enthusiasts including Leyland Mini, Chrysler Slant-6, Holden and Ford Inline 6 fans. In fact some Australian Ford enthusiasts consider the 250 2V reverse-flow head to be superior to the Honda designed cross-flow head that replaced it. The reverse-flow head is a great example of the progress of modern engineering and the influence of trends on engineering design.

Famous quotes containing the word summary:
“I have simplified my politics into an utter detestation of all existing governments; and, as it is the shortest and most agreeable and summary feeling imaginable, the first moment of an universal republic would convert me into an advocate for single and uncontradicted despotism. The fact is, riches are power, and poverty is slavery all over the earth, and one sort of establishment is no better, nor worse, for a people than another.”
—George Gordon Noel Byron (1788–1824)
