1. Head gasket on upside down, blocking oil access to the head. Make sure
you can see OBEN on the head gasket near the notches.
2. Possibly the oil pump is not engaging the vacuum pump despite the fact
that it seems to. The vacuum pump drives the oil pump.
3. Stuff sat around before the rebuild and mud daubers built a nest
somewhere. It is easier to find another block than to find the blockage.
4. The main bearings were installed without the halves with the holes in
them; or the holes are on the wrong journals, or they are installed upside
down.
Off the top of my head, that's about it.
If you really want to know if oil, any oil, is getting to the head, pull
the valve cover.
