No cheap Mopar valve springs?

Thinking about throwing a cam at my 318 and running through 318willrun's budget build. The springs he uses are the edl-5877 pn and those appear to no longer exist. I don't really wanna spend $100 on springs instead of $50, but that might just be the pandemic pricing.
My bigger question is where can I find those lighter, stock replacement style springs? Trying to stay on a budget and reuse retainers. Not to mention the car doesn't need a ton of spring, it's just a stock converter, it's not getting a big cam.
