I soon plan on doing some head work, just curious what spring and retainer combos are you guys using, I plan on using CTR cams with my turbo setup but would like to rev higher so what do you suggest?

I use REV valvesprings and they have been good too 10,500 RPM and I have made 714whp on them. Previously had Skunk2 springs and retainers and worked well for me too! I have many customers use teh Omni with luck and Supertech also. Most of these are of higher quality and work very well.
