Trey, Damm that sucks but good thing its warrantied.
I would recommend you pull the head. The rocker could have just failed, but it the valve got stuck open and the piston hit it, that piston could be damaged.
And its a cheaper fix Now if its just a dent in it, .
Drop a line, if you need anything. Hope to be dynoing this week with the test truck, see you around town.
