Chip,
If the inlet to the pump were restricted, I'd expect cavitation at the pump -
which
would show up as erratic oil pressure - especially at higher RPM. Sounds more
like
the oil galleries are draining back - what type and number filter are you
using? The
way the filter mounts with the head at a downward angle means that a drainback
valve
is very important.
