If an FE is properly assembled there is no reason why it s/b more likely to leak than a similarly-prepped Windsor. Don't forget the products used today have improved significantly since both engines were introduced and manufactured, and those newer products (e.g. RTV sealant) help a lot. Yank an FE out of an old clunker and run it "as is" and it is probably far more likely to be a leaker than one assembled today.
