Will valve springs from a 1970 Z-28 camaro work in the heads on my 400 small block?

Yes, IIRC the "z28" springs are good for .480-.500 lift or so. The are still stock diameter and don't require any machine work on your heads. A lot of places sell these as an inexpensive upgrade. Find out what your cam requires for seat pressures and buy springs accordingly.
