Not trying to be rude, but you've been here for almost 2 years with almost 300 posts and you haven't learned that there are no "recommended" settings for any kind of vocals, rap or otherwise????
You need to figure out what works best for you. Your track, your voice, your mic, your room to your liking. No one else can tell you what to set for eq or anything else. If it doesn't sound right to you, then keep experimenting until it does.
