Home Made Cold air intake question

[ChadH06]

when building the do it yourself intake there is the dump tube that runs back into the intake piping, but i also found when removing the intake there are two very smalls pipes that go into the back side of the intake piping just past the MAS.. when i read the instructions for building the intake there was nothing mentioning these peice do i need to drill holes into the intake pipe for them as well or what? if someone could let me know what i have todo with them as well as what they are for, it would be greatly appreciated.

1 connects to the valve cover - the other prob connects to a evap canister ( not sure though on a 1g ) if so, ya dont NEED them.
