I need help finding a flathead intake

Hi guys, I was just wondering if anybody out there knows of someone or knows where there is an intake with Banrey's secret ports that were casted for bonoville. Barney added more material to the intake ports so he could port them out massive for bonoville. They only casted a handfull of these and they can be easy to miss but there is no lip on the ouside of the ports like your traditional intakes. Will someone please let me know if anybody knows of one? I have cash in hand

Thank You very much guys!
