It's normal, and it doesn't matter.

theres no such thing as dumb questions...just dumb people. Youre ok

uh, well it WILL pull vaccum after the throttle opens... those nipples pull air BEFORE the throttle plate. so as soon as the plate is opened, it allows aire to be pulled thru the nipples. if you dont block them off, they will be boost leaks too.

yeah, dont use those nipples as any type of vacuum source for boost gauge, controller, BOV etc. They do not move enough air and will not work properly. Just cap them

you could use them for a Boost only guage though, like Blower pressure gauges that automeater has... youd never see vaccum though
