If it was me, using a stock block, I'd go with some TW heads that I'd do my own cartridge roll blend and polish on the ports and add some Comp behive springs+Ti retainers, a 230/240 duration cam, and a Systemax or Victor intake depending on the compression that I end up using, 85mm MAF, 75mm TB, and 30lb injectors since I'd be shooting for over 400 HP. I'd also spend a few hundred extra bucks to get the entire rotating assembly internally balanced so I can zing it up to 7000 without any worries. This is pretty much what I'm planning on after I get outa the U and get a real job so I've done a little research
