My first magnum build, advice appreciated

Sounds promising. Just wanna try the simple stuff for now. See how it works. Then go with a little more cam and maybe throttle body if necessary. Never put a tuner on so didn't know if they work or just hype. I know on my stock 5.7, a cold air intake and exhaust made a noticeable difference for a couple hours work. Didn't know if the 5.9 would respond similarly
