Problem with used Cobra intake. Need advice

So I bought a used 94 Cobra intake off a guy on The Corral and have a slight issue with it. No, there's nothing broken on it and I don't anticipate any issues installing it on the car. The issue is that when he shipped it to me he packed it in styrofoam packing peanuts and during the shipping those peanuts made their way completely up into the intake. I've used my fingers and dug out as many as I could but if I take and shake the upper I can still hear some rattling around in there. My conern is though that even if I get to the point that I can shake it and not hear any rattle it would be very easy to still have a few wedged in there only to have them come loose after it's on the car. I didn't have a change to try this over the weekend, I was busy installing an o/r H on the car, but I'm thinking that I'm going to have to pour a bunch of gasoline into the intake and slosh it around a bunch. If my memory is right, gasoline will disolve styrofoam almost imediately on contact (if not that quickly, then pretty dang quick) and with that I should be able to get rid of any last peanuts stuck in there.

Has anyone had to do something like this before? And please let this be a lesson to everyone. Don't ship or let someone ship to you an upper intake without first bagging it. The lower was packed full too but I could clean it out pretty easily. But this upper, what a PITA!
 
Does anyone have any pics of a cobra intake cut open so I can see what the inside looks like? My biggest fear is that after trying everything to get them all out that there will still be one lodged into some small crevace and that it will come loose after the intake is on the car, doing who knows what to the head/cylinder when it gets pushed in there.
 
C'mon! It's stryofoam! The worst thing that could happen is that it gets between an intake valve and the valve seat. It would just disintigrate as soon as that happened. It wouldn't live through the combustion process, so the exhaust would just "pass" it. I wouldn't worry about it. I have an Explorer intake in my garage that had peanuts in it. I got out what I could with compressed air and am not going to worry about any remaining ones.

You would be impressed with some of the things that I've seen passed through an engine with no ill effects. (Including a header bolt that was left on top of the carb. It went far enough to lock the engine up when it was started the second time. I just reverse rotated the engine until it fell out into the header. Engine started right up. I'm not the one that left the bolt on the carb. The engine is still running fine, 8 years later.)
 
Thanks for the responses everyone. I think what I'm going to try is using my leaf blower to push air through it to clean it out. I don't have access to an air compressor but I think the leaf blower moves enough air to break anything loose. I'm getting the same responses on this from another forum, if I were to use gas to disolve the peanuts they could stick to the inside, get hard, and then break off later. I'll try my luck with it this weekend.
 
i was just going to say that about the leaf blower. push the air through it like it would be on the car. shake and repeat. if nothign comes out after that, there is nothing left in there
