I know they're probably both reference but I just need to KNOW. If you could point me towards literature about reference and what isn't reference I would love to read that aswell.
P.S. If you have any suggestions please let me know!

I dont, or id tell ya. Watercooling midrange cards just isnt very cost efficient. Id try to sell them both and move to a 7950 or 7970 or 680. Then you wouldnt really need to WC anything due to the fact there is less heat generated with 1 card. And both the new gen card lines generate less heat overall. Got 2 7970s in my system and an OC 1090T and have zero temp issues with both cards maxxed out on OC as well. Watercooling is a lot of work when building a custom loop. Do a ton of research so nothing surprises you later, built my own custom loops about 4 or 5 years ago and it was a major pain in the butt to maintain.
I can't seem to find any other blocks for them though it sucks a ton, but I REALLY don't want to spend 500$ for a 680 when I only got the 6870s like a month ago
If you know of another block let me know.
Any way you look at it you will pay about $104.00 for each water block because you'll need to add the fittings too, finding the other brands in stock will be difficult, IMO for a full coverage block here's your best option.
The first card is definitely reference design, but the second most likely isn't. The cooler design is generally the same for reference design cards, but some companies' non-reference coolers actually have a reference PCB (which is the important part).
If you're looking to stay cheaper, I'd suggest universal waterblocks rather than full cover blocks.
