This occurred many years ago in my Ruby, and it was traced to a seriouslly furred up cylinder head, cauased probably by a long and exciting life in a hard water area! The solution was to remove the head and drill out the holes in the cooling passages which were a fraction of the diameter they should have been.
Take care not to remove any metal in the process.
