You probably need at least some new lifters and maybe some new valves.
The pistons may be ok though in my experience.

Drove down the road last night and the cam cog came loose.  My bet is that the valves and the pistons met.  Lesson to be learned, retorque the cam bolts after heating up the motor.  My friend explained to me that if someone in the history of the van over-tightened that bolt then the Bentley value will be too low.  The end of the cam is tapered.
