Sounds like you have tracked this down to the back of the oil pan. But just for whatever its worth:
I had these fabbed valve covers on both of my E-Headed cars with the thin, steel reinforced Viton VC gaskets. They look fantastic. But, at least on my cars, the bolts that drop through the holes in the valve covers were just barely bottoming out in the holes in the heads before getting a decent compression on that Viton gasket. It all ‘felt’ snug - but they leaked like crazy - especially at the rear of the head by the firewall. My starter was coated with oil. I ended up using a band saw to carefully lop the last 1-1/2 threads off the bolts then cleaned them with a die. That gave me just enough clearance to compress the Viton gaskets. All was good after that.
