Question about H/C/I

Hey, I am looking to do a H/C/I upgrade in the near future. Is there a site that can help me out with matching up the heads/cam and intake? I was thinking AFR 165's for the heads but then i dont know what would be a good intake or cam. I would like to acually understand why the differnent parts would work well together instead of just asking you guys each time.
I'm sorry if this doesnt make sense i tryed to word it as best as I could.

Thanks!

Danny
