Can a roller rocker head use non-rr springs and retainers?
I'm trying to decide which way to go with my build. I have a 2001 USDM roller rocker engine in my Sentra and am looking to do cam upgrades. I also have a complete lowport non-rr engine but not in the car. I've noticed that JWT springs are no longer available for the roller rocker engines and am left wondering if I can use, for example, BC titanium springs and retainers in my roller rocker head along with S3R cams?
