Help me decide!

I'd go stock iron intake, stock hermoquad carb providing you KNOW it's good, otherwise run a 600 Edelbrock. you can get them used easily, or save cash and buy a new one. I would probably leave the ignition alone for now, but eventually buy an MP replacement. Last, I'd run the Summit smaller cam. I dont trust used cams, and I wouldnt run one for free unless I took it out of a running engine.
