Cam selection help

I need help selecting a cam. I am putting my la 360/clearwater magnum heads back together soon and need some help. I am running the speedpro hyper pistons with 5cc valve reliefs at zero deck. Heads are limited to stock lift values. I am planning on running the new hughes shaft mount roller rockers at 1.65 ratio. Using a magnum rpm airgap intake and holley 670 avenger carb. Thinking about going to a 750 vac secondary holley.So to stay within the lift limits and intended use what would be a good cam? Mostly street driven 8 3/4 with 3.23 gears, occassional trip to track, spitfire headers into 2 1/2" H-pipe duals, 904tf and converter to be selected to match build. I want to keep the rpm's under 6k. Not sure if I got all the info needed so just ask and I will try to help. Thanks
