[edit] A Suggestion for clarifying the advantages of the "Hemi" design

The second paragraph of the main article states: "A hemispherical (inverted bowl-shape) combustion chamber allows the valves of a two valve-per-cylinder engine to be angled rather than side-by-side."

OK - but so what? That doesn't explain why the Hemi was worshiped by engine performance gurus. What's missing is an explanation of what difference the Hemispherical combustion chamber makes. I suggest following that first line with something like:

This creates more space in the combustion chamber roof for the use of larger valves and also straightens the airflow passages through the cylinder head. These improvements result in significantly more horsepower from the same engine displacement.
