1983 gt 5.0 resto questions.
Hey so, i'm new to mustangs, and carbed systems. I recently picked up a 1983 ford mustang gt (loved it so much). I noticed the throttle was a bit sticky and ran a little rough on the drive back to its new home. Other than that it ran perfectly. After some investigation I came to the conclusion the carb was in general rough shape, so i picked up a QFT 600 cfm carb and swapped that on. after some headaches and tuning and fiddling with it I was forced to take it to a shop to take a look at my high idle problem and major vacuum line leaks. It ran great after that, then just a few days ago I did spark plugs on it and went to start it up again to check my work. It idles great and once i put it into first (manual) it continues to idle great but once I start giving it gas to start driving, it bogs down and stalls. I have to give it full gas to keep it running and it runs rough as hell when I do that. Its not misfiring so it must be another vacuum leak.... which I don't know how that would be caused by doing spark plugs ( i guess i knocked something). If anyone has any suggestions that would be great. I don't have resources to take it back to a shop as i'm just starting school again and I would like to learn from this.

I did a quick run through on the vacuum lines with the wd40 and I didn't find any leaks, (no bubbles, or change in engine speed and performance) so I closed the hood and tried driving it and the problem continues. I haven't been able to check timing yet due to canadian weather so on a warmer day I will do a more thorough walk through on the vacuum lines. But could a leaking intake manifold gasket cause, or at least contribute to some of these issues?
