Machinist that built my engine strongly recommended against aluminum rocker arms on a street engine unless they were replaced every couple of years. Steered me to a set of Comp Cams Pro-Magnum steel roller rockers. Don't need stainless, they won't rust bathed in
oil, just the chromemoly ones. ~$250/set (Summit). Comp Cams even recommends rebuilding the arms every 50 thou or so with new bearings and rollers, but the arms will never bend, break, or wear out.
Using the Pro-Magnums on TFS heads, no problems so far. TFS's are unique in getting the roller tip centered on the valve tip needs to be done carefully, and adjusted by moving the guideplate around to get it right. Just dropping them in won't align them properly.
