it's not really that bad to change out the injestors, but you will need a new plenuim gasket.. I'd also replace both the upper and lower O-rings on each injector as well as the little screen on the injectors.. If you get them from a junk yard clean them real good with brake cleaner.. not carb cleaner as the carb cleaner will make the plastic parts brittle..
