I test fit Comps, PRW and RAS rocker arms on that engine. The Comps worked the best. They all fit with beehive springs, I think the RAS arms would've worked with standard springs but I don't recall.

Most people aren't able to test fit multiple rocker arms on an engine but I've found that with Mopars it is the best way to go. The various rocker arms all fit very differently. They are not interchangeable regardless of what people say.
