The old notice it has a true hemispherical shape.
The new notice the quench pads on either side of the valves, no hemispherical shape. Sorry this is so small but its the only one I could dig up.

Nice pics, and he will definately hear the semi-hemi the Monday at work. Im not going to open my mouth unless he does. After I heard about the semi-hemi I googled it and read an article from Popular Hotrodding about the new hemi. They said they couldn't use the true hemispherical shape due to it not making any power with high compression. The hemispherical shape works the best under boost. I dont remember all the specifics, but thats the basics of it.
