Ok, if you all want to see what a real Hemi head looks like, goto this link,
it has an awesome picture of the head. Notice that the combustion chamber is
a complete circle "HEMI", and is a dome, like most all heads! It is not Half
a circle, it is however about half a sphere!! That is what a Hemi is!! The
4.7L valves are positioned just like this picture, but it isn't a true
circle, there is a small flat spot on the circle.

Actually it means half of a circle (Hemi = semi and sphere is a ball),
The dome at the top of the cylinder is actually a dome shape (like half
of a softball) in the 426 and 528 Hemis.
