Valve springs

Ok maybe I jumped the gun a little bit. The hmm thing kinda got me. I'm just taking a 383 with stock heads other than new exhaust seats and I put those springs with matching retainers. But had to use original locks because the comp ones that came with it had different grooves. Arnt there springs that people have put in stock heads that can tell by those numbers that I will be fine if I'm not to hard on them. I can't drive the car for a couple years have to get brakes done and body painted and in that time I could get a better cam and spring set.
