I just pulled a customers head apart to check his springs since he didn't know the specs of them. This is on a 24v puller. The springs had 68lbs of seat pressure at 1.380". This is a concern since factory springs have 78-81lbs at 1.380" If you are running these, beware of running the r's or the boost too high. Valve float is almost for sure on a hot engine.
