Can I run stock rockers?

Lunati recommends adjustable rockers on the next smaller cam, they don't say anything about the 60403 but I'm sure it would be recommended, it has .513 lift on the exhaust. After doing all this cam research it seems like most of the manufacturers recommend adjustable rockers even on the tiniest of cams. Was planning on using the Edelbrock springs that were on the heads, they are a single spring with 120 seat pressure and 320 open. The heads allow for .575 lift. My main concern was pushing a rod through a rocker. I'll check out the thicker stamped rockers. I just don't want to spend any more coin on this thing if it will be fine with stockers.
