Please help: car will run, but won't idle

Hey,
So I recently bought an '87 IROC-Z Camaro with a 305 TPI v8 it. I had blown head gaskets so I tore the engine apart with a mechanic friend of mine and did a full gasket swap on the car. The car ran fine before this other than overheating and leaking oil. We got it all put back together, but now we can't get the car to run without giving it gas and it won't idle obviously. We have the timing adjusted just right and we unplugged the MAF and it sounded even worse. I'm pretty sure everything is hooked up and secured down properly. Any ideas? I'm seventeen. This is my first car and I've already got close to 3,500 in it. Your knowledge and help would be greatly appreciated! Thanks.

Edit: Also, I got the heads resurfaced and got a valve job. The car has sat for three weeks now if that makes a difference. I changed the oil and coolant. It seems like she's running rich. I've got coated headers instead of an exhaust manifold. My exhuast system is fairly new. The battery is fairly new. The spark plugs seem good. We have the timing top dead center towards the first cylinder. We didn't fully take the injectors out and replace the o rings. We only unplugged them. We left the fuel rails on the intake manifold and didn't mess with the EGR. All the gaskets are new and in place. The fuel lines are tight. I just don't know what it could be. I need it up and running soon though to drive to work.

hey. its a long shot, since it seems you got everything else right. try checking the voltage on your throttle position sensor. yeah, simple, but i had to start my car with carb in the intake once and i was led to believe it was a fuel issue until i checked the tps and replaced it. hope this helps since no one else has replied.

Thanks! I'll give that a shot. I'm not very familiar with electrical aspects of the engine. I think I'm gonna see if I can adjust the idle speed as well. Cause it idled quite low before I took the engine apart anyways. I might also see if I give it gas for like five minutes if it'll warm itself up and establish the right pressure. It's been sitting for three weeks so it might just need a little nursing back to health.
