I replaced the head gasket on my 1927 six, I notice that the previous owner tried to use a modern type thermostat in the housing, it was a 160 degree unit, but it doesn't fix correctly between the baffle and housing. and it was installed upside down. The only way that they could make it fit. does anyone have an option for the six cylinder thermostat? should I not run one.
