If you're staying with a stock camshaft, there are hundreds of options! I often use (and really like) a set of factory Z06 valve springs (PN 12249224) and Comp 787 retainers and 7 degree locks. I use these in a lot of the Vortec truck engines that I build where you're not running a ton of camshaft. They're certainly not a racing spring, but you don't need one and with a stock cam, they're a great setup for the $$$.
