wow, I gotta check in here more often

yes, you can do just the lower but you are missing the chance to get ahead of the game on vacuum leaks. FelPro sells the kit with upper stuff included for a reason. Get the ones that have a part number ending with "T" as they have the metal frame gasket. Check surface around coolant ports for pitting and get machined if it's excessive.
