They are just a stock type cast dished piston. probabily a 15cc dish volume.
The stock compression height is 1.56"

Re: anyone know what pistons are in here?
.025" you can get a decent 9.8:1 compression ratio using a 58cc head with a thin steel shim head gasket.
Milling your 62cc head to 56cc and using the same .015" gasket will get you 10:1.
