SB roller rockers

I am looking for a Decent set of roller rockers for my 408 build. I've run into so many extra expenses so far so I would like to not buy top dollar rockers. With my luck I probably won't have a choice! I was looking at the mancini rockers and shafts. I always thought their stuff was good quality. Has anyone used their roller rockers and how did they work out. Is the quality one that will last on a street/ strip car. Probably only race 2-3 times a year.
Thanks Rodney
