Throttle Shaft Lube?

Do I need to lube the throttle shafts on my new Holley carbs? I've had issues in the past with OEM carbs (not Mopar) that have worn in this area & caused vacuum leaks. If I need to lube them, what do I use? 3 in 1 oil? Silicone spray? Graphite? How often? I just don't want them to wear prematurely, they cost a bunch!
