Can I remove the EGR valve from a quadrajet carb? Also, what else can I remove from this diagram? How do I strip the carb of all emissions related (and other useless) things?

I think the top "p" port on your carburetor is just a port into the intake to apply vacuum comparison, and your TVV applies vacuum to EFE (early fuel evaporation, dumps it into the manifold) and opens EGR when the engine is warm (aka no EGR on a cool engine). The EGR valve proper would modulate that flow... or something. The EGR operates when that valve opens, but un-operates (if that's a word) when there isn't enough backpressure in the exhaust. That whole loop could probably be removed without killing anything particularly, but the EFE side might be nice to have, I don't know. Might flood when hot without. You'd probably do alright just yanking the EGR and plugging its port on the TVV.
You want the DS-TVS in place (distributor spark thermal vacuum switch) and presumably the DS-VMV (distributor spark ?? valve, probably spark advance). SVB-tvs = secondary vacuum break thermal vacuum switch - it breaks vacuum for some thermally related reason, so probably helps running in some respect.
No, I don't really know what I'm talking about - but I can fake it okay with a search or two.

The EGR isn't integral to the Q-jet.
That diagram looks like one for a 301 4bbl where there was an EGR adapter under the carb.

Just keep track of what you have done, so it there are any problems, you can go back.
