Update: 2/26/2011.
I brought my car back to them, and gave my friends an ear-full. Frankly, there is no other repair place in my town where I'd take my car. I have a lot of faith in that shop, and they do know what they're doing. This was just an unfortunate happening, my first with them since both me and my dad have been going there (a long time). But anyways, they agreed to fix their mistakes, for free. They plugged up the hole which was drilled to deep and fixed the valve cover gasket which didn't lay right near the carb.
I picked it up yesterday, and started it up...It sounded good, a little uneven at idle, but that's how it was before I had the valve cover put on. I didn't have much time to look into it further, I had to get going to work. So I drove the car to work at 4 pm. I got off at 10 pm, and started to drive home. I came to a red light, and when it turned green I gave it quite a bit of gas...in which killed it... I restarted it, gave it more gas again and it really died down and almost stalled again. So now, it's getting to much gas, so I assume the timing is still off. Also, my windows were fogging up terribly, so I turned on my defrost. It didn't do anything, and all I could smell is anti-freeze. And sure enough, there it is all over the carpeting of my Eagle...Heater core must've taken a crap.
I don't think they had anything to do with the breaking of the heater core...but seriously... how much more time and money is this car going to take from me??
