Those pistons are a hypereutectic version of the stock flat-top piston. It mimics the older style long skirt 350 piston. It is NOT intended for performance use.

The skirts are broken because of too much piston-to-wall clearance or because of careless installation.

If the bores are too big, the shorter skirt pistons will rattle like crazy.
