HKS cams (264) only have around 11mm lift if I remember correctly, so you probably won't need uprated valve springs. I think once you start getting into 12+mm lift then you need heavy-duty springs, although someone please correct me if I'm wrong. Are you keeping the RPM limit standard?

good standard springs and retainers are fine as above post
ideally check spring height to make sure they fall within spec
