Throw them away and buy new valvesprings, used valvesprings even if matching is a poor idea.

As I recall, yellow sound like the original LS6 stock spring that had many failures. The blue were replacement LS6 springs. Not sure why you got a mixed set but depending on the cam, they may not be adequate for valve control anyhow. What is the cam?

Just buy a set of BTR springs for $229 shipped and move forward.

Just talk to a vendor you trust about what cam you have THEN pick an appropriate spring to buy.

the spring are new they came off a set off ls6 stage 2 heads from some company, but they upgraded springs for a monster cam

Some "budget" companies will use new OEM springs as a positive selling point without regard to the fact they may not be appropriate for the cam.

Springs have to match the cam and there is more to it than lift capacity.

If you want NEW stock springs good to .570, just buy these. At least you KNOW what you have at that point.
