Well, I think the Harland Sharp idea has merrit. but, to be honest, most guys dont need roller rockers, and aluminum rockers of any sort will break eventually. For a street car, where budget and mild cams take precidence, the Chevy parts are fine. They do adda a certain amount of stress to the stud. as you can see in the pics, the factory has a flat to flat joint, with each 1/2 helping to stabilize the other. I think using guide plates and hardened pushrods would do a very similar job, even under abuse. But, the pedestal style fulcrum will be ultimately stronger. Question is, is the $2-300 difference in price worht the stability? That depends on budget and usage.
