There's an important difference between the nosecone/camcover gaskets on the case breathing Shovelheads and Evos and later model head breather gaskets.

Another important difference are the holes in the gasket at about the 9 o'clock position. If you put the earlier gasket with the extra hole on a late model engine you won't get any oil pressure to the top end. Very important difference.
