4.GREAT

I'm getting a new cam for my truck and I'm not sure which springs to go with. The chevy performance ones say they support up to .570 lift while the 918s go up to .609 apparently while my cam lift is only .561/.566. I'm not sure if its hard on the cam lobes or anything else if the cam lift is nowhere near the max lift of the springs or not. Would it be fine to run the chevy performance ones since they are much cheaper or would I be risking broken parts? Which springs do you guys think i should go with?

My truck is a 2002 Sierra with a 4.8 and I have it revving to 6000 rpms max right now but I'm thinking about going a little higher to 6400ish after the cam swap.
