This picture was found at this link, but doesn't match the 4 valve relief description either:

I'm wondering with a 10cc dish, if this picture could be right with the valve reliefs taking up most of the volume. The picture shows a flat top in the quench area, but only 2 valve reliefs.
A two valve relief SBC FT piston generally won't be over ~5cc.
