Sounds like its plain worn out.
Ring seal,or valve seal are non existant
or so it seems.A bad lobe would only affect
1 cylinder.
Did you do the compression test the right way?
Dry. then shoot some oil in the plug hole and redo it.
Does it pick up any cranking pressure?
Seeings how its all 8 cylinders I would think either rings,
excessive bore wear,or valve seal is gone(valve job at best
or heads at worst).
Does it still have the original heads on it?If so I would bet the
exhaust seats are gone unless someone put hardened seats in them.
