BME Aluminum rods

Actually the rods set is brand new, never used. The purpose of this engine is racing only.
About the pistons I can have a set of KB846 at summit for $400, but custon pistons can cost more than 50%?! Am I right?
Another question, Would BME make 2 diferent forged Dies for those rods? One for .927 pin and another for .984?

Best regards,
