Rocker adjustment

i am not trying to argue point. these are just things i have ready or been told.
im still learning this... would i be better to just run stock rockers? im running the Hughes Whiplash cam.. intake 0.480/ exhaust 0.516 with 1.5 rockers... im just going off what i have read in different books and online forums... lots of people i have found ran these rockers with aluminum heads and a 0.480 and bigger cam... i want it to be right.. im trying to just get it figured out... even when i put the stock stamped rockers on with no pushrods they are as close as these to the springs. other than shims how could i get the rockers farther from the springs? they fall where they fall becasue they are on a rocker shaft..

Some more reading that will make it obvious what YR and Cruze are talking about:
