torque wrench

If you plan on owning your classic car for a while then you should consider investing in a torque wrench. There's a torque specification for pretty well every nut/bolt on the car so you will use it again and again. If you only ever changed the oil and grease on the car, why are you installing an intake? As others have mentioned, it's handy when putting wheels back on. If you need to put all 4 back on, that's using 20 times in one job!
