I've been reading alot about ppl using G8 (L76) springs and retainers for their rocker setups. Would i be able to use these springs for my setup with a VS cam? I've had the cam about 6 months now, but never changed the spring because i wasnt sure which to go with. Also even though it probably wont be anytime soon, if i chose to get an XP cam, would the L76s work for that?
