Mopar 360 kb 190 Pistons

have a set of 360 kb 190 for sale... Two years old less than 1000 miles on them, just pulled them out running engine... Reason for pulling and selling is I used stock heads with high compression pistons and Burning oil... Found out using wrong valve stem seals and I was choking my engine with the stock head... Bought closed chamber heads so goin to flat head Pistons... Asking 300 obo and will send pics if you pm me.. They have oil stains and little scratch marks on the piston skirts but no damage and would not hesitate to reinstall them back in my engine.
