Probably none of it. The valve springs have to be stock for the motor you
are using. If it is a 1992 motor, it ALL has to be a 1992 motor unless the
part you change is specifically noted as unrestricted in the rules (like an
intake manifold, for instance). Sorry, valve springs are not unrestricted
in SP.
