Partly plugged radiators are very common. Grease, rust deposits, lime, and loose rust flakes afflict many old radiators. It can be very difficult to get one clean. Some radiators with straight tubes can be "rodded out". I don't know if the honeycomb or cellular style can be.

Water pumps can leak air in at the shaft seal and cause overflow and overheating problems. This can happen, especially at higher engine speeds, even if the pump doesn't leak when sitting. A clogged radiator can aggravate this condition.
