First, I don`t mean to high jack the thread I apologize if so. This is why I like this site so much so much great information here. I`m glad this subject was brought up. I`m in the process of firing up the 1955 235 engine. I don`t have a heater, I plug the thermostat and water pump side outlets. After reading the discussion, it stands for reasoning to have that even flow under the thermostat. I purchase 5/8 hose, the heater extension 3/8 threaded nipples and a dummy heat control valve. From the thermostat housing and water pump the heater hoses would travel like if it were going to the heater. This gives the appearance of it and not having a short loop connecting the pump and thermostat. I know this is alittle over kill. The dummy heat control valve connects the two lines together circulating the water back. I`ll mount it somewhere under the battery holder on the fire wall. Again Lemmm117 I apologize bringing my story in your post. I felt I had to bring it up. Steve
