I did this job a month ago, and it doesn't need the head removed. I used one of Lancer's nitrided chains that should last longer than a stock one. It would have been easier to get the cam/cam sprocket in place if I had removed the bolt that secures the rear chain guide rail....that would have provided a bit more slack in the cam chain.
This is a very good time to cure the oil potential oil leaks and retorque the head. Use a Versy head plug, remove the left front and right rear cylinder head stud nuts and washer, clean them up, apply antisieze to the threads and a small amount of Suzukibond to the top and bottom of the copper washers, as those can weep oil (remove the left rear and right front cylinder stud nuts and clean them and use antisieze...the sealer is not necessary on the copper washers). Remove the cylinder head nuts under the intake and exhaust port, clean them and apply a bit of antisieze on the threads and a small amount of Suzukibond on the shoulder of the nut.
