Yes you can use Patriot or PRC dual springs on stock heads, these are beefy springs that are usually installed with big cams (like the MS3 for example).
A double roller isn't something that is usually required, but is installed for extra insurance. Most op for a new LS2 timing chain and call it a day, but there have been documented cases of breaking them. But I don't know if they were related to harmonics imbalance or not.
