Are you looking through replace the stock springs with stock springs?

I'm not getting what your asking or your what your intent is.

I am moving up to a.540 lift cam. I believe the stock Edelbrock springs will be ok. I am looking at max rpm around 6 grand. The springs I have now float, previous owner changed them. Open to suggestions but I want a drop in replacement.
