The head will have to come off, regardless. Never does a timing belt skip/break and no valves get bent. OP will need a 10, 12, 14 and 17mm socket, as well as a 10mm hex bit to remove the head. Have fun with the two 14mm bolts on the underside of the intake manifold.
FYI, it's best/easiest to remove the head with the fuel rail, injectors, CAS, both manifolds and TB/TBE attached. Pull the valve cover, the 4 bolts to turbo, the two 14mm headed bolts on the intake manifold bracket, the water lines to the TB, fuel lines at the rail (4 bolts), oil line to the turbo, the water neck (held on with 3 bolts) 3 bolts to the front timing cover, and any vac lines to the TB, disconnect the entire engine wiring harness and throttle cable, pull the 10 head bolts, and remove the head.
Should take about an hour, tops, if you've never done this before.
