What brand is the cam, ie I need to know how fast the ramp profile is, if it is a Hughes or something with a .904" Chrysler fast lobe on it I would not run the stock E head springs on it, they're just not up to the task pressure wise. Just because a spring can "handle" .580" lift does not mean it has enough pressure to deal with fast ramp speed or heavy valvetrain.
