It looks like Comp has two different springs that will work for the Duramax. The 26125 is the heavier spring, and the 26113 is the lighter spring. The 26113 looks to be very close to the same price as the SoCal springs.

Is it lighter to the point where it's not heavy enough?
I have no idea. They're 258 lbs/in vs 191 lbs/in. If SoCal does in fact use Comp's springs, it makes me wonder which ones they use.
Seat #'s Depends on the set up hight....I know each .025 set up change can put seat #'s up quite a bit.... But then coil bind plays a big part.

FYI there are only a few spring manufactures in this country. everyone buys from one of them, unless there bought overseas....Which i know some are.
So how can one go about positively identifying the SoCal springs as Comp Cams springs? I'd like to save some money but don't want to screw myself with buying too light of a spring or one that won't work with Comp's seats and retainers.
You're asking a near impossible question. They aren't going to give up the part number and why should they?
