Yes you do have to remove the radiator, you can actually rotate the A/C condenser up and out of the way.
You don't have to remove anything else in front of that.
yeah, just remove the rad, slide the ac condensor out of the way (no need to totally disconnect it). I removed the water pump while it was still attached to the timing chain cover as well. Saves you some time since you won't have to reinstall the water pump later. It will come right out (no need to remove the front bumper)
remove your upper and lower intake, remove your valve covers, pull your rockers and push rods, and lift your roller lifters up out of the bores.. then slide the cam out.
Oops.. just read your title not your post but I'll leave this anyways
