what are you talking about lower port or one above it? There should be 2 ports for the KS's btween cylinders 1 and 2 and btween 3 and 4. Are you looking at your injector holes? I thnk the KS's go below the injectors on the block. Are you looking at ports on the head? I really dont know what you are talking about, there should be 2 unused spots for them.
