Default After engine rebuild car started, but will not now.

Just finished up a engine rebuild (bent valves). Replaced the heads, new head gasket, turbo back exhaust, headers, perrin crankshaft pulley, and perrin intake. The engine started, idled till i turned it off, but ran rough with the alternator and ac belts not on. I put the belts on today and now the engine wont idle like it would before. Its almost like its not strong enough. It cranks, fuel pump comes on, and it starts for a split second, but then dies. I was thinking it was the plugs (i didnt double check the gap when I put them in), but am open to suggestions. The only sensors not plugged in are the two oxygen sensors because I am waiting on them through the mail. Holes are plugged though.

I can picture that if your primary O2 sensor isn't plugged in that it will want to crap out because it thinks there is something wrong.
