"Educated Guess" values have been recorded from Corecraft test server which isn't a primary source (credit for that research goes to NiM and Shiro). However, when I've tried to verify some of their values now and in the past, they've come out pretty much right and in my opinion are preferable to any guessed values and can be used for the time being until primary sources are studied.
For now I'm just trying to establish plausible values for the mobs. Documenting (pre-nerf) fight mechanics is beyond the scope of this post and as far as I'm concerned, should always be based on retail evidence rather than trying to replicate Corecraft. Bosses may have higher health than values I can verify from primary sources. That may represent state before from when raids were still wiping, or it might be custom tuning. Both numbers are provided.
As an SSC-specific note, most trash mobs appear to have values almost twice to what they had in 2.4.3. The thing is, at least for Beast-Tamers and Colossi there ARE sources for values that are double to datamined ones you see in wikis and databases so it seems very likely to me all trash were similarly tuned in the beginning even if I can't find a source, and subsequently I haven't bothered in finding verified values (the fallback is 2.4.3 ones anyway). For bosses it's also perplexing: it's well-known some bosses were absolute bonkers before being fixed and it's possible there used to be some evidence for the CC values, possibly from before world firsts or at least from before first videos where I can get an estimate of the health. However, while some individual details like Greyheart Spellbinder health can be verified despite not appearing in guides or wikis giving credence to all values being backed up by some retail sources, I can't prove a lot of CC-values. It's well-known SSC was unfinished when guilds first entered it and Blizzard tweaked it on the fly and even extremely inflated numbers (say, Karathress health) seem plausible with this in consideration. But the problem is, I can't find proof of those numbers. If you are making a server, you can either assume they're pre-world first values with bugs fixed (knowing that primary sources probably don't exist any longer and Corecraft is the only surviving secondary source so you just have to trust it), base your custom tuning upon those values regardless of their origin, or you can use verified ones.
If you want to reverse possible custom tuning, dividing melee damage by 1.3 wouldn't be too far off. Verifiable health values for bosses is provided.

I tried to verify damage values from those videos (world 6th and 7th kills respectively). Really annoying because random resist amounts and damage debuff, I can't definitely say CC values are wrong but looking at the numbers they feel like they're on higher side of things. Adds seem right compared to evidence

Educated Guess, WoW Bestiary
World of Warcraft Bestiary isn't the go-to source for instances (for starters, Karathress damage is clearly too little even for post-nerf) but I don't see how many instances of WF hit in videos so it's difficult to determine damage and 10-14k listed in Bestiary seems about right

Video sources have some very big melee hits, CC damage range seems plausible after a quick look. I cannot verify health. However, Corecraft has the unkilled version of the encounter with spell reflecting water elementals and such like so they clearly had evidence I'm not aware of.
Method video shows damage higher than post-nerf values. I don't see health but it feels higher than the verified values as well

Nihilum kill screenshot displays Vashj shooting for unexpectedly high damage so increased damage seems plausible so I'm just leaving it as-is. I can't find a source for 8M health.
340k health mentioned in the blue post isn't the same as CC values but neither is 145k for post-nerf (which would be 175k). Corecraft values seem to reconcile these two conflicting sources at least. Damage range seems plausible looking at Method video.
Each Colossus has random elemental vulnerability, one of three possible sets of abilities and five possible effects upon death. Quote from Wowhead describes the mechanics:
Frenzy and Atrophic Blow:
This is the easy one - just have a hunter remove frenzy with tranq shot.
Acid Geyser and Parasites:
Folks in melee will get a debuff that ticks for ~2k for a few seconds, then a Serpentshrine Parasite will spawn from them (they have 1hp, thunderclap kills them). Rogues can cloak of shadows the infection off.
For Acid Geyser, just have the whole raid stack up right outside of melee range behind the colossus. When the colossus changes targets to use acid geyser, the one person who is being targeted simply runs through the colossus to spin him away from the raid. After the effect ends they jump back in the stack.
Spore Quake and Rampant Infection:
Just outrange spore quake (30 yards). Try to assign someone with a good ping to catch rampant infection when it starts jumping around the raid so you can avoid losing people to that. Rampant infection does more damage with each jump, so it will eventually oneshot someone if it is around too long (As a minor consolation, dying to rampant infection doesn't give a durability hit since the damage technically comes from a player).
Since all the abilities are in sets, it's easy to tell which major ability they have (Quake, Geyser, Frenzy) by looking for the minor ability. If sommeone gets rampant infection then you know it's going to be spore quake. If melee gets parasites you know it's going to be acid geyser. If you have decent communication about the abilities you can almost always have people in the correct positions before the big damage abilities fire off.
When the colossus dies, one of several things can happen. This isn't tied to what abilities they were using while alive.
Nothing.
Two big adds spawn. These need to be tanked.
8 or so little adds spawn. AOE these down.
Toxic Pool - the ground turns bright green and starts doing damage. Run out of the slime :)
Blue mushrooms spawn. These put a heal/mana regain over time on you when you get close to them (if you run in and out of range you can stack the buff several times).
They're all weak to a random element - you can have a mage use detect magic or just wait to notice that someone is doing a lot more damage then usual.
Vulnerabilities
Each mob has a random 100% vulnerability to nature, fire, frost
Abilities (one of three sets chosen randomly for each mob)
Set 1:
Athropic Blow 1313-2187 nature damage, reducing str/sta by 30 stacking 30 times. Proc chance seems to be 100% on melee hits
Enrage Reduce time between attacks by 150%, can be dispelled by tranquil shot.
Set 2:
Serpentshrine Parasite Deals 3000 damage per 2 seconds for 10 seconds and them releases a Serpentshrine Parasite. Parasite tries to crawl to a new host but can be killed, having only 1 HP.
Acid Spray Deals 2188-2812 damage
Set 3:
Spore Quake for 1292-1499 and casts knockdown each tick (30yd range)
Rampant Infection deals 3000 damage and after 1.5s jumps to a new target within 10yd (1). Damage increased by an unknown amount each jump, can be dispelled.
Death
Upon death, colossi trigger a random death effect:
Create Toxic Pool dealing 2138-2362 damage per tick
Blue Mushrooms spawn with Refreshing Mist, restoring 9-11% health and mana per tick.
