[Three Peaks]

May be a stupid question, but what rockers are you using? I had a set of lifters (Scorpions, I think) that would bind on the springs before they came to full movement because of the way they were radiused on the spring side. Put Comp Pro Magnums on and plenty of clearance and the issue was gone. Approximately same symptoms. My springs were also .650 rated lift and my cam was around .595 total lift.
