I'm picking up a 01 ls6 cam from a buddy of mine. He said I could have the stock springs for 20 bucks more, but they are blue springs. I searched on here and googled them but with no luck. I just want to make sure I can use these in my truck? I don't mind spending the money on some yellows but I figure if these are interchangable why not. Also the cam and springs only have 20k on them.

Thanks for any help!

Edit, with more searching I think I have answered my own question. The blue springs are just rated to app .550 lift while the yellows are rated around .560-.570?
