Using your exsisting lifters and pushrods with beehive springs is about as RIGHT as ya can get.
If ya just got to throw money away,throw some over here.

FFT. Just cuz a pushrod is hardened does not imply that it will not bend. What it does, is allow it to return to it's original state more dependably over nonhardened rods. Stiffness is a product of diameter moreso than hardness.

I forgot to include wall thickness in above post as well. It's just that there is more to flex than the 'rockwell'. Aftermarket are or can be thicker walled in addition to greater hardness. I'd get them primarily for that feature. Then if that were not enough, go for larger diameter.
