stage vi valve gear

So Ive bought a set of aluminum mopar stage vi heads.They have max wedge size ports,a 74 cc chamber and require offset intake rockers. I was lookingat hughes Edelbrock Victor head ofset intake rockers,which claim thye have a max .600 offset. This is more than enough offset for the maxwedge port and Im thinking they will work.

Whatcha think? They look like aluminum. While I would prefer ductile iron I cant seem to find them anymore. Does Isky still make them? I know crane no longer does. I'll likely also need adjustable rockers to get the geometry right,as well as shims. Adjustable pushrods might be a good idea too..
