LS9/12625033 valve springs
 

I'm putting an LS6 cam in my 4.8, and I found a set of LS9 springs that are rated to handle the lift of that cam. Do I need to buy the retainers and locks that are listed to work with those springs, or will my stock hardware work with them?

i used my stock hardware with the ls9/ls6 springs

Thanks for the quick answer, George.
