More info: They're new covers, seals and bales from GoWesty
(http://www.gowesty.com/ec_view_details.php?id=23641&category_id=&category_parent_id=)

When installing, the gasket fit well and the covers were snug with no
rocking or anything. I'll try the steps below, and if that still doesn't
work I'll look at using some gasket/sealant stuff.

Thanks for the advice everyone! Now if only this rain would stop so I can
get to work without getting soaked. :-)

I would make sure everything is flat and clean. Then glue
the gaskets to the valve covers with spray adhesive.  Then I use a thin
smear of grease on the other side of gasket that
seals to the head. The gaskets last a very long time this way.
You may need new bails and covers if they lost tension/bent.
Busdepot used to have some OEM covers. I know GoWesty
sells a kit that uses all repro parts. I have no experience with
GoWestys kit just seen it advertised.
