gude gorilla cams or crower 403's, and dont forget the valvetrain.....get yourself an aem intake, a kamikaze hedder and an exhaust system before you get the cams. motor needs to breathe. your looking at roughly 10-15 on average. you can put in new bumpsticks w/o upgrading the bottom end, but at least do arp rod bolts and head studs if you plan on high revs.
