I would check that you have in fact got the #1 ignition lead in the correct place - a quick check would be to remove all except #1 spark plug, and check where the rotor button is pointing when on this compression, turning by hand.
If this is correct then recheck that you have the direction of rotation and order correct.
If nothing found, then check that points are opening about right. One thing that can cause problems is if the flexible lead that carries movement of the breaker plate is broken, so that you are relying on chance earthing. Also, look for bad or intermittent connections anywhere in the low voltage ignition circuit - typically engine/chassis earth, if the coil is on the bulkhead and the battery earthed to the engine, or the ignition switch itself.
And even though you have recently replaced all the ignition components, you may still have faulty ones - symptoms could be anything in the ignition, but especially the coil, capacitor and leads. And have a look at the plugs, since they had the head off - look for damage or incorrect gaps. And there is a slight possibility that it has ended up with the wrong plugs.
