    intake manifold

    I'm curious to know if it should be polished to a mirror finish or do I need to leave some porousity in it.

    Rough. It atomizes fuel as it travels through.

    i used to leave my car intake mani's with a 800, take a welding rod, bend it over a few times run the sandpaper through and put the other end of the rod in a power drill... run it kind of slow through the intake and it makes somewhat simular to a hone etch inside the ports... VORTEC BABY
