You dont have a perfectly symmetrical pattern to work with but you crisscross up/down in multiple steps & end up going thru your selected pattern 6 or more times and I have better luck w them ending up being tightened less than what I think they should be (lightly snug) & definitily using your choice of sealer

I use the red high temp sealer on both sides of the gaskets. Finger tighten all of them or in your case lightly tighten. Let set for 1/2 hour, tighten them 3/4 of a turn. Leave them alone.

Cork gaskets are the only ones I use, and the only ones I could ever get to seal. Silicone the gasket on the valve cover side, and snug with a nut driver. Not so much as a seep!

A lot of people overtighten valve covers and oil pans. The nut driver suggestion is a good one. I prefer "glued" the black ultra seal gaskets to the valve cover with Permatex Ultra-seal after straightening the valvecover metal, especially around the holes. I then coat the side that touches the head with a wet coat of motor oil and tighten evenly with a speed wrench taking care not to over tighten. I check the bolts occasionally and keep them snug.

If you are running stock exhaust manifolds, it may be cooking the gasket along the lower rail. I think there was a shield or special gasket made to provide a solution to this?

It isn't rocket science.
I prefer the silicone coated steel shim gaskets, but I have used all the commonly available types.
I have almost never used RTV, a crutch for poor workmanship, imo.
Flat rails, on the cover and head, fresh gaskets and properly torquing to spec is all that is needed. I might use a spray glue to glue the gasket to the valve cover to ease installation, but I have also used thread to tie the gasket to the cover.
If you get into aftermarket intakes or covers then you prefit and check for issues, fix them and install as above.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Those steel shim silicone one's don't work on the SB with stock covers.
