Hopefully some our other experts will weigh in on this topic. I don't have any direct experience with your issue, but let me say this. A Corvair with standard springs will ride higher than one with HD springs designed for the same application as I remember. So I wouldn't expect a HD Corvair front spring to raise your car up as high as you expect. If you haven't added much extra weight to the front, Clark's should be able to tell you the ride height for a new HD front spring. Maybe the answer is to lower the rear spring height.
Good luck with this
