Carb to throttle body conversion help

[Aftermarketfreak96]

I have a 1987 chevy k10, that has a 350 in it with a quadrajet on it, and have had nothing but problems with it. Since I'm getting ready to rebuild the engine, I'm leaning towards putting throttle body back on it since I have all the wiring and the ECM for it, but am wondering what all I will need to convert it. The previous owner put an 85 engine in it, so I believe I'll need a different set of heads because I've heard the tbi manifold won't match up with it, a tbi assembly, map sensor, egr solenoid, coolant temperature sensor, a knock sensor, oxygen sensor, tbi distributor, and an electric fuel pump. Would appreciate it if someone who knows about this can confirm this is all I need, or if I'm missing something. Also none of my gauges are hooked up, so I don't know if this will play a factor or not.
