SAC wit a small nozzle hole. is my preference. your 12 valve was designed with 5 hole injectors at 145* spray pattern. a 7 hole injector was originally 24v stuff. you can read in between all the lines of hocus pockus about better spray pattern and what not from the 7 holers in an old truck. my personal experience will vary from the next guys so take it all with a grain of salt. but 7 hole injectors are dirty POS's compared to their properly sized 5 hole cousins. shoot me a PM with your phone number and I can send you some videos with some proof and injector sizes.
