you can get a box of fittings at a local auto parts store for around 3 - 5 bucks. on the meth kits i have ran in stalled over the years, this is what i had to go get.

 

Break off the nipple on the port on the passenger side of the head. Its perfect for that size tube

 

Are you using a meth kit without forced induction? If so, you shouldn't be hooking up a vacuum refference. If you are NA I think you will need a controller that works with your mass air sensor. Sounds like the kit you have has a boost refferenced controller. You won't have any boost to refference so it won't work.
