JW, you're right of course, it can be an issue. But the 150-160 stats were a necessity in the era of methanol antifreeze [pure methanol boils at about 65 deg. C (150 deg. F)], but with water or EG antifreeze that's not a concern. These engines will run quite nicely at 170-180 but since it's an unpressurized system, that doesn't leave you much upwards margin to the boiling point. If the cooling system is in great shape, a 180 should be just about marginally OK.
