Glad I found this thread. What happens when spring pressure is too stiff for selected cam? I have some untoucheded 906 vortec heads. Cam selection .520/.540 lift with comp 26918 springs. Recently comp revised the said springs and now has an open pressure of about 380 lbs. I was advised to go to a softer spring (26915's) by comps tech advisor at factory installed height. Just curious as to what could occur.
