I did mine during the initial diagnosis without removing the timing cover by following the shop manual procedure, links are below. I did have to unbolt the cam bearing caps and lift the cam in order to remove the VVT actuator/sprocket and install the new one. Good opportunity to inspect the VVT oil passages in the camshaft are clear...carefully so as not to nick the bearing surface. I used a can of compressed air and plastic straw, gunk came out.
NOTE: I did not remove the exhaust cam, and I don't recall removing the exhaust sprocket but I may have needed to in order to get the side chain off and free up the intake cam lift height. Tie off the main chain to prevent it from falling into the timing cover...I used a large zip tie to secure it to the engine somewhere.
