I don't think even Marlin would agree with that statement. The high-flow 333 version is felt by many to be optimal. But I do not believe it is mandatory for satisfactory operation. YMMV, of course.
The 333-180 is correct for the Cleveland (has the hat) AND it is a high-flow design as the original Ford thermostat was.
You will easily be able to locate a Cleveland-correct (has the hat) thermostat. Locating the high flow Cleveland-correct version is where the trouble starts.
Thus Marlin and his well-needed cottage industry.
