How is the water distribution tube? Is it clogged or missing. Also check that the water pump clearance is correct. Too large of a gap and it could be subject to cavitation, and not moving enough water.

The next would be the flow rate of radiator. Even though it was fitted with a new core, if the new core was as thick or efficient as the old one, then it wouldn't have the same cooling capacity.

How's the timing? If too advanced then that can cause overheating.

How's the exhaust? A partially clogged exhaust can also cause overheating.

Are you sure the heater valve is closing? Is not it can recycle hot water back into the motor.

Lastly a bad head gasket, cracked block, or warped head can cause hot cylinder gasses to leak into the coolant which overheats it.

Good luck!
