That is an indication of some kind of blockage. If the hoses are new and core was cleaned and checked that leaves the valve as the most likely culprit and it is probably not opening.

If the heater or valve leaked and had been bypassed at some point with a hose directly connecting the nipple on the head and the return on the water pump there is a slim chance there could be some kind of plug in one of the nipples. If the water continually short circuits thru the bypass hose, it will never see the radiator and overheating can be an issue. In most instances something is inserted in that hose to restrict or stop any flow. That something could have migrated and got stuck or maybe was even purposely inserted in a nipple.
