With everything else that you've put into the motor I don't think it makes sense to leave the ignition system stock. I'd upgrade the plugs, wires and coil with high performance parts (I prefer ND Iridium plugs & Magnecor wires personally) and go through the distributor thoroughly, making sure the advance mechanism is working properly & installing a quality cap & rotor.
