Um....you sanded them?
with what? how much did you take off? are you sure of the integrity of the piston? you have less material now so there is going to be more heat. Your compression ratio will change as a result, and each cylinder is not going to be as equal as possible as intended by original manufacturing. What exactly do you mean by "ding"
Why are you using arp head studs? Is there something wrong with the stock hardware?

I've notched pistons for valve clearence. There is no issue if you smooth the edges. I assume this is a street engine. The small mark left in a factory forged piston will not effect your engine. Even with an occasional spirited romp.

The factory piston isn't forged, its cast which makes it more
brittle than a forged piston. As badly bent as some of those valves are , the damage to the pistons could be extensive.... I'd also think about checking the rod bearings after a smack like that.

my valves don't look like that... all it did was skuffed em up a little bit... and one had a diny ding in it.

regurdless the pistons arnt being repplaced i was just wondering if there was anything top end related that should be cleand/repplaced
Id buy a new motor for the price of getting new pistons

well got everything back together accept 5 valve cover bolts. And ran it for 3 minuts and then shut it off and draind the oil and filld it back up. now i have to bleed and change the coolent out. the only thing im worried about is the head not haveing water in it and getting hot but i guess there is nothign i can do but run it and keep adding water.

As long as the dents are not too deep, I would not worry about the pistons. If some metal was swedged up, I would smooth any sharp edges out or you may get detonation.
Good luck, tell us how it worked out
