Could also be the valve seals failing too. Or the PCV valve sucking too much oil. I don't know where the PCV goes into the intake tract, but if it primarily goes into runners 4 & 8 then your problem's more likely the PCV doing it.

I do not know about a 351, I do know that a 302 has this problem if the rear gallery oil holes are clogged with sludge. The oil will fill the valve cover and drain down the valve stems to the top of the cylinders.
