I still don't like the springs. Mopars have push rod geometry problems to start with. Why compound the issue and say, "hey lets let this rocker go where ever it wants to". Like I said before I spend hours setting up a set of rockers so the side clearance and sweep pattern is exactly were I want it. It can't move with spacers and aluminum hold-downs limiting it. I then scribe each rocker and spacer with their proper position. If for some reason I am rushing at the track and have the shafts off no mistakes can be made.
