" Only other way oil can get in to the intake runners ( "intake full of oil" )is a bad seal between the heads and intake manifold"
How would this happen with a Indy Valley pan on a BB???

Oil coming in through the PCV hose."

Not trying to be a wise guy Crizila but how could the oil from the pcv valve in the valve cover going either to the carb or a fitting in the intake manifold via a hose be affected by the seal between the manifold and the heads on a bb with a valley cover? If the oil were introduced into the hose by blowby or getting sucked past the baffles it would get directly into the top of the manifold before it ever came in contact down where the heads and the manifold are sealed would they not???
