Default I'm confused

After I got my long tubes, plugs, wires, and MSD 6A installed my car has been throwing code 64(Lean, O2). What do you think caused this, and is there any quick fix so I can get my car running better?

Check the O2 reading to assure the ECM is going closed loop. Otherwise you may need a heated O2 sensor.

How do I check the O2 reading, and also I know one of my O2's is heated, I'll check the other two tonight.

Bad, all three of your 02 sensors should be heated(unless they were replaced by non heated)

Yep, they're all heated.

Do you guys know how many wires the sensor plug(into the block between plug #'s 6 & 8). Mine only has one wire plugged into the back of it, but it looks as if there should be two wires(I think mine's green).
