sounds basic, i know, but check your connections to the fuel injectors real real close... make sure contact is good...

double check that the plug wires are reinstalled correctly on the distributor and plugs.... may be out of order.

Put the car in a dark area and with the hood open, run the engine and observe the area around the coil and spark plug wires. If there is any blue glow or arcing present, you'll find your culprit. BTW, it is a common mistake to re-install the metal spark plug boot shields incorrectly. Make sure the tabs are not wrapping around the spark plug, That will cause a voltage leak and misfire. I am a fan of Taylor firesleeves to cover my plug wires and boots. They will resist a direct header contact.

Its very hard to get it back together perfectly on the first try when you do all of that. I'd go over it and make sure you have every sensor hooked up plugs in the right order ect. Also what heads did you use and what size cam? A bigger cam is going to have a lopey idle having it tuned especially a dyno tune can really help but it will never get it all out if its a big enough cam. You may just have plug wires crossed or something simple that was a fairly big job to do just go back over and double check everything.
