Permissions issue with Sites migrated from SharePoint 2007 to SharePoint 2010

I have a SharePoint 2007 collection That I am an Administrator on but not a site collection administrator on. There are some sites that I do not have the ability to edit.  It appears that inheritance has been broken on several subsites.  This SharePoint 2007 collection has now been migrated to SharePoint 2010. I am the Farm Administrator on this SharePoint 2010 collection.  However, the sites that were previously inaccessible to me in SharePoint 2007 remain inaccessible to me.  I thought, that as a Farm Administrator, I should have access to all sites. Is there a way for me to gain access  to these subsites?  The access I need is the ability to edit the pages of the subsites.  

Note: Migration was done by Database Detach/Attach migration.
