i had a valve spring break a while back and the piston hit the valve. the valve is clearly bent and the piston got cut up a little bit. the cuts are not that deep and i didnt see any cracks or anything. here is a pic below. what do you think should i run it or not?

 

It doesn't look too bad. If it doesn't feel too deep it should be ok. If it was my car, I would sand the rough spots down where the valve hit just to smooth it out.
