Aren't the valve cover bolt holes on a Hemi to the inside of the gasket rail? Here's a picture on the following website to show what I am talking about.

If that is the case, then the entire gasket rail would be totally cut off on the intake side to reach the valve cover bolt holes. I can see where that would be an issue when someone building hemi heads cuts the head back far enough to remove the gasket rail and the valve cover gasket has to be seated to the intake manifold or to an added spacer. That is just flat wrong and any head modified like that should be DQ'd.
