318 LA build

I'm currently building a 73 Swinger and using parts off my 72 4 door Valiant. The 318 was built bone stock about 4,000 miles ago and intended to run in the Valiant. Unfortunately I got T boned by a 90 year old geezer just weeks after rebuilding the front end.. Bright side is I finally bought a 2 door :)

My goal is to wake up my 318 without going too crazy. Can anyone suggest a good intake/carb set up and a mild cam that will run nicely with stock heads? I'm also looking for headers that will fit decently around my power steering box. Thanks in advance!!!
