good dual spring for .670 lift The cam I will probably be running is ~ .660. Hydraulic. What would my spring choices be? This is on LS7 heads...factory installed height is 1.980 or something...vs 1.800 for LS1/LS6. Should I still go with 1.800?

You have nuts of steel Greg.. 
They flow great...but not any better than any other head out there at .550

I have a set of NEW unopened Ferrea's sitting at Synergy, good for up .660 lift laying around. Paid $550 or so. Say $400?
If you want to go higher, I would be thinking triples, which is a little harsh is street ride.
PM me if interested and/or just call Synergy.

BUYAMERICAN...I looked at Ferrea's website, and those springs (S10008) are only rated for .620 lift, not enough for what I'm doing. Also, $400
I think I'm going to go with Cam Motion K-Motion K800. $120
Open = 165# (1.850 installed height)
Closed = 470# (1.150)
Bind = 1.085
1.460" diameter
good to .700 lift.
Question: are the Morel lifters able to handle this spring? There should be zero problems keeping the valves closed with these springs, ti intakes/sodium stem exh

Greg,
I just looked on their site and you are correct after checking the item number you posted..I am going to have a word with the vendor in Texas that sold me those .660's whith are really the .620's at $550. I am not particularly happy about that.
I am more impressed with the springs below. That is a fantastic price. Let Rick know how they work. You might want to check pressure and coil bind before you install. .700 is pretty impressive for a double.
We use the Comp R lifters, I am not sure about the Morels.
