Yes the little ends are unfinished as they come. They are a press fit into the little end of the rod, then need accurately machining to size afterwards. Not a simple job!

They will need machining to a tolerance that leaves .001" oil clearance oversize compared to the O/D of the gudgeon pin

Any less they wear/seize any more they rattle
