Replacement 68 340 four speed cams

Does anyone know if Ken has these available now..? i keep hearing about supply chain shortages and parts not being available. i have a 340 ready to build and would like to use the 68-4 speed cam
If you have a cam core to send him no need to be concerned with supply on his end, pretty sure the cost for a regrind being bandied about here is based on you supplying the core?
