We can suffer very cold temperatures in the winter and I have always drained the cars if I am not using them daily.
The 90 year old head is made of very good quality aluminium and repairable, it has provided good service over the last 15 years and many, many miles of hard use. The gasket had not failed and even worked perfectly with all the nuts removed!
I have lost some low down grunt with the replacement head - nice and quiet though!
I saw a friend of mine yesterday who has replaced a 37 head on his Chummy with a "slope milled" early one (a la Malcolm Parker style). He said that it goes just as well.
