will the engine turn over by hand in either direction ? If not you are gonna be taking the engine apart to check damage.

was the engine running when it stopped? If no, damage should be minimal. Maybe a new piston and a quick hone at the most.

I would say go with OEM if you want to spend the $$$, its going to be the best. Or see if anyone makes an aftermarket cast aluminum piston. Dont bother with wiseco forged aluminum. For the money you can get an OE piston which will be better in EVERY way than a wiseco.

Yes go OEM pistons , Are you going to just replace the one or are you going to do them all ?

Since the screw was all the way down past the piston and there was a broken piece, you should check for metal debris, so none will not get into the crank bearings. Buy a gasket set and re-ring the other cyclinders and hone them good.
