I really don't think drilling holes is the answer nor trapped air as the root cause problem as Chuck described, but, it is your tractor and you can do anything you want to it. Over a half million N's have survived without mucking with the OEM design so it's your call. Overheating a radiator is usually the result of overfilling, underfilling, or plugged fins. Perhaps you need to take it in to a radiator shop and have it boiled/cleaned properly. One other point is the OEM thermostat originally had a clamp on the hose to keep it situated closer to the engine, in the lower part of he hose. Ford eventually discarded the clamp, but many use a regular hose clamp or the cheaper plastic wire ties to keep it from creeping up towards the radiator top.
