Speaking of opinions, I have a couple about your advice. Yes, there is a good reason for thermostats, and only one reason for no thermostats: On a race car, the restriction costs horsepower.

Coolant moving too slow, again, I agree. Once an engine reaches operating temperature, open up those thermostats.

Too fast? I do not agree. That is an old disproven theory that attempts to explain another racing trick to save horsepower: Remove every other vane in a water pump. An exception to the too fast theory is when it causes cavitation.

Finally, about a flathead never getting up to operating temperature. Really? That doesn't happen except on a very cold day, or while descending from a mountain. the harm that will do is extend the warming-up period longer than it need be, which isn't good for any engine.
