These are the valve springs that should be with my cam (well, heads):

p/n 73121 per Summit.

Number of Springs Per Valve: Dual
Outside Diameter of Outer Spring (in): 1.526
Coil Bind Height (in): 1.150
Damper Spring Included: Yes

Inside Diameter of Outer Spring (in): 1.135
Inside Diameter of Inner Spring (in): .775

Here is the application and what I remember being written on the heads (the 140lbs part)

Recommended Camshaft Style Flat tappet solid

First off, the pic (which probably doesn't tell much), makes it look like one. But, I can take these apart and use the outers only to break-in, right? Or is this spring rate not to 'heavy'? I don't really know the difference, so thought I'd ask so I can learn. Thanks..

Yes; you can do that with virtually all double springs. Having the damper makes it a bit more of a PITA sometimes, but still not impossible. After all, they got them together somehow.
