Dan is talking about a second set of springs that apply force directly to the lifters to help keep the lifter from floating, so the valve spring is only working against the inertia of the pushrod, rocker and valve. The two sets work together to keep the valves from floating. They are available for Big (and small?) Block Chebbies, but I've never seen a set for an FE.
Big problem an FE would have is, what would the springs push against? The Chevy rev kit springs push against the bottom of the cylinder head, but the Fe has no cylinder head "bottom" to push against, since the pushrods come out through the intake manifold. I guess they could push against the manifold bottom, but how the heck would you install the manifold?
Anyone have any ideas?
