Do not get sucked into modern points conversions, if you do, keep your original breaker plate so when you un-convert you have something to use that works. Also a misfire is generally not associated with a knock. I would like to see how you position the spark lever when driving. Is there a secondary fuel filter? Have you tried to isolate the knock by shorting cylinders under load? I agree wit others, go through the dist. and check the oil pump/ dist, drive gear tooth wear and slots on drive shafts. These are the small things outside of the mechanical insides of the engine. Divide and conquer one at a time, fix correctly what you find.
