Yes they are shorter in over all length, you really don't notice it though until you stand the game up on end. Gottlieb called it "street level" pins but in reality they were produced to save money on wood, weight and materials. Making the game a few inches shorter would not make an operator want to buy the game as they were waaayyy behind the times compared to Williams and Bally in the same era which were making far better games that people actually wanted to play. People only played those Gottlieb's at the time because the other games were filled with stacks of quarters on them. Gottlieb was very old school and felt they could compete with the old "less is better" thing. Turns out they weren't further from the truth and within ten years from the end.
