When replacing the cam with a higher performance unit you should do the Cam Kit route.
New Springs, rated for your cam, new pushrods, all for two reasons.
1) being the manufacturer’s required length for the new cam, based on their manufacturing process (this applies to both the Springs and the pushrods) and 2) being the higher rpms you will be running and valve float so higher rate springs will be needed.
If this is just an OEM Spec replacement cam then new is good just in case there is something wrong with the old stuff and you wouldn’t want to get the engine running and have a pushrod or valve spring fail.
