100 Dollar Hemi!

I've been looking at getting the comp cams HRT stage 2 cam Stage 2 HRT 220/230 Hydraulic Roller Cam for Dodge 5.7/6.4L HEMI w/ VVT 2009+ but I've heard their valve springs are not the best. I've seen some recommendations for these, http://www.americanmuscleperformance.net/PSI-1511-57L-VVT-HEMI-Valve-Spring-Kit_p_2075.html any advice as to what to go for?
