Sold separately, must order 2 to make a set. Most commonly used in the hemi engines, but are great to also use in Honda/Clone or Predator Non Hemi heads. Can be used with stock valves and retainers. Best suited for CL-1, CL-2, CL-3, Cl-4 or Mod2 grind cams when using stock 1:1 rockers. If using ratio rockers these springs may need to be shimmed depending on application.
If you are using stainless valves you will need to use our heavy duty retainers, part number DJ-1047 or DJ-1047t.
Give us a call or email if you are unsure or need recommendations on the combination you need.
