Go ahead and use stock injectors if you want...but the car is over 23 years old, you might want a new set, as the originals are on their way out.
Get the 36# ers. Give it the extra fuel it needs; and that way youll be running disc injectors too, not pintle; allows for a better spray and less clogging. For the love of God (and the car), dont use the stock injectors. It will save you a whole lot of hassle down the line.
