Generation IV Internal Engine - Yellow beehives in L92's

I got a set of brand new 821's that I picked up. They are complete, even have the rocker stands and rocker arms. These heads have yellow beehive springs in them. Are these what people refer to as LS6 springs?
I am going to be putting stiffer springs in, can I sell these brand new yellow springs and pick up a few bucks?

TIA

My LS3 springs are yellow. I think they are the same as LS6 springs.

You might get 25 to 50 bucks depending on the day.

Springs in my LS6 are yellow.

they are $60 brand new. Still worth 30-40$
