Years ago there was a study that indicated straight water ran up to 30 degrees cooler in a non-pressurized cooling system. In addition another study more recently said long-life anti-freeze could cause gasket damage and subsequent leaking. A friend who built Model A engines would not warrant them if using anti-freeze.
I run water and drain in the winter but don't drive when the weather can go anywhere near freezing. I simply add water pump lube/rust inhibitor.
P.S. The "old green" antifreeze probably would be safer though not cooling as well as straight water.
