Don't worry, you will be fine as you are taking the correct steps and learning how to do things properly. Personally, I would never fire a rifle I build without checking headspace either. Hope these videos help.
Just another day in paradise. I’ve watched about 15 ar10 bolt disassembly videos and I’m scratching my head.
I’ve taken the bolt apart. Removed the ejector roll pin, ejector pin, spring, etc. then reassembled the bolt (minus the ejector related parts) to check headspace. I put my “Go” gauge into the chamber, pushed the BCG and it won’t lock on the gauge. I figured headspace was off. Tried the “NoGo” gauge and it didn’t lock either (good news). I scratched my head.
I then pulled the BCG out of the upper. Took the “go” gauge and popped it under the little tab that holds the cartridge by inserting on a small angle and pushing down, it fits (see first photo) and then put the BCG with the gauge locked in place into the chamber and it full locked into place. I did the same with the “no go” gauge and it wouldn’t lock.
I am unable to get the bolt to lock on either gauge as the little tab on the face of the bolt won’t open/move enough to accept a bullet/gauge? I pushed pretty hard without any luck. But again, if I put the gauge into the bolt prior to inserting, no problem.
EDIT: so after watching a few more YouTube videos, I realize you need to put the go and no go gauges onto the bolt under the extractor prior to trying to check the headspace. So my understanding is that my headspace is all good, as the GO would lock into place and the NOGO would not. But I still need to figure out where this spring came from... keep reading
So I took the bolt apart again and found this tiny little spring inside the bolt, and after watching another dozen videos I can’t figure out where the heck it came from??? Where is this tiny spring from?? Perhaps it puts a little tension on that tab that isn’t moving?
The extractor itself already has a small spring in it, surrounded by a rubber gasket of sorts. I tried putting the little spring inside that spring, without luck either?
This might not make any sense. But help, please

Where is your ejector, I don't see it in the photos.

Sounds like you did ok with your Headspace check. Next time take the extractor off too as it makes it easier and is much better for your precision gauges(remember, they are delicate and you shouldn't even let them fall hard into the chamber). Also, checking headspace is much easier to do with the barrel out so, if you ever do another build, check it before you torque in your barrel.
The small spring goes into the large spring in the extractor like you guessed.l(duel extractor spring). You may have to try it both ways but, it will fit as that's where it came from. The O-rings stay where you have them.
I bought the jig in the link and it worked great, thx for the link jiffx!!
I recently bought a heavy barrel in 6.5 creedmoor, the gas block journal is .934”...Does anyone know where I can get a gas block jig for a heavy barrel .934” gas block journal?? The jig in the link will work up to .750”ish

You can always use a clamp on. It’s pretty easy to eyeball them.

Or...
Here, TNA has them in stock right now in Canada...

Thanks guys, TNA seems to have the .936” jigs in stock and I ordered one.
Its good, but definitely not suited for the rifle its on. I intend to put a Zeiss 5-25 as soon as my scope mount comes in.
The Trijicon is a beast, it seems built to survive the worst one can throw at it, but considering its a 1-8 FFP the reticle is awful bulky at max zoom. Not a precision scope IMO.
It will likely go on a 223 bullpup or a MS upper.
