In cold water, a 143 degree t-stat will cause the engine to be very inefficient, running rich. In warmer water, as long as the oil cooler isn't clogged and is checked regularly (which is mentioned in the manual), a 160 degree t-stat will be just fine. Running at 180 isn't a problem and will never trigger an overheat. It will, however, keep the engine from running rich and wasting gas. In extremely hot air and warm water, the t-stat will basically run a bit open a lot of the time if the recirculated water makes it necessary.
On an LT-1, the 143 degree t-stat is like a pre-heater for the raw water and keeps the engine from experiencing a bad thermal shock when cold water hits the hot metal.
Also, we were told to use 160 degree t-stats when we went to MC training- the manual is for original specs and won't usually be changed unless something major calls for it. In most cases, the service bulletins cover any changes that are necessary and aftermarket manual printers don't always get these.
