More info is needed, some cams and valve springs may have to have more relief area in the rocker boxes

The '07 and later OEM beehive springs will accomodate cam lifts up to .600" lift. They are not heavy springs, IIRC, about 135# on the seats and, for most cams, will control the valves at the higher rpm levels for a typical street build. If the application is aggressive ramps and drag racing where high rpms are the order of the day; a spring with more seat pressure would be a better option.

Screamin' Eagle® Valve Spring Shim Kit, 18226-03 You can alter your spring pressure with shims like pictured here, have used these in many builds with good results. You want to have your orignal spring pressure tested first:s

AV&V, Bob Wood(PSI), Crane, and the S/E(Comp Cam) springs are all good.
At one time years ago, Bob Wood had K-Motion providing him springs............THAT, was a genuine nightmare!:nosad
