I was wondering if I can use the yellow ls6 springs with the ls9 cam. Cam specs are 211/230 .558/.552 122 lsa. How long will the springs last. The stock ls6 cam is 204/218 0.551/0.547 117 LSA. The lift is not that defferent.

ThanX

 

From what I have read in the GMPP catalog the ls6 springs are good to .570 lift. Hope that helps.
