How did this not blowup?? Suzuki LTZ 400 head/ valve train issues

What going on everyone? I just got back from Northern Idaho helping out RSRacecraft build some of their Mini jet boats. Such awesome mini jet boats.This 2005 Suzuki LTZ 400 had some major valve train issues. Another shop attempted to put in a new valve guide but failed. How didn't this LTZ 400 motor not blow up is pure luck. Unfortunately I once again last some footage. It happened to be some of the most important.So it's time to upgrade my recording equipment.
