I just took my upper intake manifold off (see picutes) and my throttle body. very dirty excited to port and polish!! but im wondering about the lower intake. the 6 holes the upper intake lead too..they are also dirty and i would love to clean as far into them as i can but worried about all the crud getting into the motor...how do i go about cleaning it, should i just leave it, should i try to use a vacuum and polish at the same time or what? thank you

I would just leave it. A pnp you'll need to pull the entire mani off. Just leave it the gains are not worth your troubles.

 

itll bug the poop out of me but i think your right! the real reason i did all this was to just look at the throttle body and possible get a larger one and then i saw how dirty the upper manifold was so i took that off to clean it as well.
