Our 1929 keeper runs around 160 degrees even on a hot summer day.
After a 15 or 20 mile drive with 20-50 oil in crankcase, oil pressure is still around 3 lbs. engine is hot, but you can still touch head. You can touch radiator. Not for long though.
We do not use thermostat and use water only with rust inhibitor. Dripless water pump. I know I have written more than needed. Sorry. Enjoy.
