The washer idea comes from back in the 50s/60s. It was believed that slowing the coolant flow down gave it more time to exchange heat in the radiator. Don't think that idea holds up, but IMO at higher rpms the volume of water flow can overcome the rate of flow through the radiator cooling tubes and get pushed out the overflow. These early flathead cooling systems are non-pressurized.
160 degree thermostats are sure better than nothing. 175-180 would be much better and 185 to 190 range better yet.
