EASY???? OK what are you smoking???
replacing the cams is not an easy job... changing the sparkplugs or wires that's an easy job.... I think you will find there is a little more work involved than you think like taking off the timing belt and then removing the cam gears and then the cams along with all the parts needed to take off to get to these... I would guess a cam changes is a full days of work or more considering the timing belt is about 8 hours to do....
