Back to basics with my 86 305

[Sovereign]

I want to remove what's left of the emissions components on my truck. What's still present is broken switches and sensors, dry rotted vacuum hoses, and hoses not even connected. Instead of arrogantly ripping it all out sure that it's not needed, I figured I better ask what needs to remain.

So, does any of it need to remain? I plan to keep vacuum advance, cruise control, AC, PCV, and would like to keep the charcoal canister to keep fuel vapor odor under control.

Looking at the schematic sticker on the core support, it appears I can remove all of the valves associated with the air pump, EGR, and heat riser valve. Is this correct?

What is the tip in vac switch on the firewall and can it go?

Is it possible to keep the charcoal canister functioning without the valves?

What is the distributor delay valve and can it go? I've only had older engines with vacuum advanced connected straight to the valve on the distributor.

What should I do with any electrical connections that I remove? Without a computer, there are no fault codes to be concerned with. Are there any functions that would be lost if I remove the tip in switch for instance?

I appreciate the guidance.

Thanks
