I've been down this same route with cast-ion heads, Ersons, both cast aluminum and pent roof valve covers, both cork and rubber and all the sealants. The mix that works for me is cork gaskets and Permatex Right Stuff. I clean everything up and use RS to glue the gaskets to the VCs. I have some little plastic clothes pin-type pinchers I bought at Home Depot to hold down the stubborn area of the gasket. I also lightly smear a coat on the inside edge of the cork with my finger so it won't soak
oil in once its mounted. The RS dries in about 15 minutes so you don't have to babysit it long. I let them sit overnight and dry. I then run a 3/16-1/4" bead of RS around the sealing edge of the head, NOT THE VC. I use two pieces of 6" threaded rod in two of the holes as pilots and slide them on. Snug 'em up to about 10-15 lbs, run a couple of heat cycles and tighten them a tad again. No leaks ever.
I am running whichever Holley jets that are the equivalent of .070 restrictors in my cast heads with solid lifters. I have a set of the Kirkham clear Lexan valve covers I used when testing and I went from having 3" of pooled
oil in the VC at idle to about an 1", basically just above the VC-to-head seal. You can see the
oil pooling in the head towards the end of the clip:
