... there is one other thing to look for ... the cork setup has valve
cover studs with shoulders to establish the proper spacing between the
VC and head.  Most of the rubber parts have built in spacers that look
like washers.  These spacers will stack on top of the shoulders, so the
spacing between the VC and gasket is too much and leaking occurs.  If
you have this situation you will very likely get oil leaking at the
seam.  You need to switch to the appropriate studs if you have this
situation ... 

... am I the only one who does not understand the " I don't understand
how it's only on one side of the engine, and not the other" question?
