Unhook and plug vacum advance and see if it smooths out will be down on power but should run smooth if its knocking cause of too much timing.

The kit you need for stock hei is a dizzy recurve kit they sell at summit and jegs. Get one with vacuma advance lockout and mechanical advance lockout. If totally stock dizzy get a kit with a coil and modual as well.

You can do a search for the pics of the install. Everything is easy to do and you can find directions on the forum on how to install.

What about fuel filter and fuel level in float bowls. I really do think its fuel but kinda sounds like your timing is set wrong as well.

You can buy a new dizzy with all this stuff installed but tis always needs tuning and they dont reallly advertise which kit comes with which options so i always use recurved factory one.
