Had similar
oil consumption problems with mild 460. I replaced my valve stem seals as well, but that had little effect.
Turns out the root cause was the intake manifold gaskets weren't properly sealed, allowing
oil to be sucked from the valley into intake ports. Drain coolant, pull the intake manifold and carefully inspect the gaskets for signs of leakage.
