Default Valve cover leak question

I have a pretty good valve cover leak right at the back corner on the passenger side of my engine. 65 GTO with older 87 cc edelbrock heads, new enough to use the updated head bolts but old enough to have the old-style chamber.

Do Pontiacs generally or these Edelbrock heads specifically have a tendency to pool oil at the back of the passenger side valve cover? The weird thing is it doesn't seem to leak much when the car is running, but when I turn it off I come back the next day to a pretty good drip onto the passenger side header.

Does enough oil stay up in the passenger side under the valve cover after shutoff to cause what I am seeing?

Thanks!
