Need h/c for ls1

Just got married and the wife now says I can spend money on the car since the wedding is over. I can't spend too much but can spend some. I wanna get a good head and cam setup for my 2002 camaro ss. I have the msd plugs and wires, borla cat back exhaust, slp headers with the slp intake. I wanna get some power but not want too go too far out there.
