But you aren't the OP. Far as I can tell, the OP doesn't need anything fancy. A set of used Isky nodulars would probably work just fine for what he is trying to do. If he can't find them then the best alternative on the market these days is the Comp steel rocker arms. One of the cars I help tune has a set of Comp steel rockers on a 505 big block with a fairly big solid roller. Engine makes 750 hp and the car runs 9's every weekend at the track. That is probably pushing it for Comps but they have lived okay for several years on that engine so they'll handle anything the OP needs.
