have a blown head gasket is my guess
it could be the water pump or a blown head gasket
did you check the radiator or the head gasket?
I had replaced the water pump and radiator. This had continued to overheat but not as bad. After replacing the head gasket it was finally fixed. I was able to answer my own question only after replacement.
the head could be warped BUT try removing the thermostat because that could be a bad thermostat try running it without it if its a blown head will not have compression and the oil will look milky
Have the heads and head gasket checked possible thermostat in backwards
Intake manifold may have moved when being tightened down causing intake gasket to move and not seal. There are water passages in it . I pulled the head and the gasket had moved, replaced the gasket and this time used permaseal this fixed the leak.
