Just wondering if you cleaned up your radiator neck. The casting is 3/16" thick. I found my spare and it was in poor condition. It was covered with deposits inside and out and looked like a item from a shipwreck. After a few minutes at the wire wheel and many more cleaning the inside, it looks good with plenty of life left in it.
The engine I removed this from has sat for 20 years and the entire inside was full of hard deposits that had to be removed with a hammer and screwdriver. There is no radiator or water pump that can cool an engine in this state. I pulled the piston liners and got everything super clean.
My local radiator shop showed a 4 core for the JH so I had them put it in. No cooling issues since then.
