Answer 2

Building on this answer I gave to a related question, I would suggest the following query:

SPListItem lastItem;

try
{
    using (SPSite objSite = new SPSite(sSiteUrl))
    {
     using (SPWeb objWeb = objSite.OpenWeb())
     {
      SPList objList = objWeb.Lists["MainHeads"];

      SPQuery objQuery = new SPQuery();
      objQuery.Query = "<OrderBy><FieldRef Name='HeadID' Ascending='False' /></OrderBy><RowLimit>1</RowLimit>";
      objQuery.Folder = objList.RootFolder;

      // Execute the query against the list
      SPListItemCollection colItems = objList.GetItems(objQuery);

      if (colItems.Count > 0)
      {
       lastItem = colItems[0];
      }
     }
    }
}
catch (Exception ex)
{
    ...
}

return lastItem;

This assumes that you are executing the CAML in code. IF not, see F. Aquino's answer.
