Whats the consensus on valve cover gaskets?

You even seen those gaskets? No. Then hush up ya cheasp bastid.
No I've never seen A $64 gasket and I don't want to! And yes I'm a cheasp. My last $9.95 "improved" cork lasted til I changed them last week. or change them because they just seemed like they were getting those little flat and the gaskacinch wasn't holding them to the valve covers anymore. And of course I have my self-proclaimed Priceless valve covers LOL
