 Sounds to me like you had/have two problems: first, bad plug wires, which you fixed; and second, something wrong with the front carburetor, which remains to be addressed.  When were the carb balance and mixture adjustments last made?

On the other hand, problems with the rotor and distributor cap are not always easy to spot, so if you have new spares on hand, you can try substituting them (both at the same time) for the parts currently on the car.  Bad plug wires allow the development of very high voltages inside the distributor, and this can cause carbon tracks which are often hidden from view.  And humidity inside a distributor, whether or not combined with such carbon tracks, can cause a broad assortment of peculiar problems.

If you were still using points, I'd suggest checking the points gap for all four dist. cam lobes, but you mention having a Pertronix.  As a fairly remote possibility, perhaps two of the magnets in the rotating part have broken or are covered with something that would affect the device's operation, thus giving a weak or untimely spark. 

You may also have low compression on cylinders 1 and 2.  If you haven't done a compression test recently, it's certainly in order now.
