The short answer is yes if for no other reason for retension time of the fluid in the rad to transfer its heat.

I have one but I cute out the center and put it back in, so it's just the housing

As above, yes. The thermostat is designed to cycle open and closed. The coolant circulates around the engine absorbing heat until it reaches the opening point on the thermostat. The coolant is then allowed to flow out of the engine outlet to the radiator to be cooled. The coolant that was being cooled in the radiator flows into the engine to start absorbing the heat from the engine ready for the next transfer/cooling cycle.

Engines have a temperature range in which they get the best performance and economy. Also, things like oil and internal parts to the engine operate and protect better in a certain temp range. If no thermostat is used then that range could take longer to get to or not be acheived at all. In which case performance, economy and engine wear characteristics could suffer.

Go with a least a 160. You do need to get it up to temp for best performance, less sludge etc. and moisture rid etc. Also it keeps the water from being moved out of the radiator to fast. I would drill a small 1/8" bleed hole in the 160.

This gives a slight bypass and prevents air locks.
