It seems like it's very easy to bend the valves this way. I had a slight intake valve leak after hitting the intake valve when I set the timing. To be sure you should do your leakdown test on another cylinder to compare the exhaust hiss from it. You can also take off the exhaust and listen for the hiss at the port. If you spray some WD 40 on the back of the valve so it runs into the seam between the valve and the seat you will hear it bubble when the cylinder is pressurized. You will not need to replace the valve guide but you will need a new valve and have the new valve lapped in or the seat cut (your machine shop should be able to advise you on this).

One other thing to check before you go through all this is to look for a vacuum leak on the intake of that cylinder. Maybe swap the injector as well with another cylinder to eliminate that possibility.
